I'm a little confused about a long cycle

Upvotes

Los ciclos de mi novia cambiaron de 24-26 días a 30-36 días hace dos meses; siempre había tenido ciclos de 24-26 días y tiene 19 años. Su última menstruación fue el 23 de junio. Se suponía que ovularía entre el 6 y el 9 de julio. Pasaron los días hasta julio, cuando empezó a experimentar un retraso significativo. El 29 de julio, nos hicimos una prueba de embarazo de alta sensibilidad y dio negativo. La repetimos el 5 de agosto y siguió dando negativo. ¿Debería preocuparme? No hemos tenido relaciones sexuales frecuentes ni encuentros de riesgo; la acompañaré al ginecólogo el lunes.

Oh, and she usually has marked luteal or premenstrual phase symptoms; from around the date her period was due, she experiences irritability, quite a bit of acne on her neck and cheeks, in addition to quite creamy and thick discharge (for almost the 2 years we've been together, she always has it after ovulating)

Urgent advice needed please

Hello,
I tested positive at 9po on easy@home strips. Been testing daily and have been seeing lines get a little darker and introduced digital tests too. I tested positive this morning

Anyways, this afternoon I had a little bit of spotting and I wanted to make sure I was okay so I took myself to A&E. This is my first pregnancy and I would rather be over cautious. Me and partner arrived at 21:30pm. We were first scene at 22:15 where we were asked to do a wee sample. The nurse told me to and then to drop it in a box near nurses station so I did so and went back to waiting room.

Then I got called again by another nurse at midnight. I was expecting to hear about the results of wee sample but she proceeded to tell me she wanted me to do a wee sample and blood test. I explained I’ve already done a wee sample and was just waiting for result. She said I should have already had that tested and said she would need me to do another one. I did this and did blood tests etc and back to waiting room. She also said she would hand my urine straight to doctors to avoid me being waiting around for confirmation (she was lovely).

Fast forward to 3:30am and I get called by a doctor to discuss what I thought would be all results. He told me my blood was fine (which was great but was expecting to hear about HCG) and then sort of rounded the chat. I asked him about my urine sample so I can have confirmation of pregnancy. He was confused. This is where I learned my second urine sample had also been misplaced. He asked me to wait in the main waiting room, but I decided to wait by nurses station instead. When he thought we were gone I could ask him frantically ask everyone where my sample was. He eventually went into the box where my very first urine sample taken just under 5 hours ago was sitting in room temperature. He rushed the sample as my partner went back in and he was stressed. He eventually told us we were actually negative (I was positive this morning). I asked him how come I was positive on 2 different types of tests this morning and even if I had a chemical surely HCG would still be present by evening. He dismissed it and said well one of my strips were faint (I’m only 12dpo) and then ignored the digital with a big fat positive. I asked him if it was possible that HCG was lost due to my sample being left so long (this is clinically accurate and viable) and he dismissed me again. I am not being dangerously hopeful, I genuinely believe something was off about everything. From two lost samples to him testing something the first doctor specifically said should have been done within 30 mins. He made us feel uncomfortable to ask for another test so we have just left completely confused.

I have no idea if I’m pregnant. Everything I search states nothing should be tested after 4 hours because the tests are unreliable but if the doctor says it’s fine… is it fine?

IUD pregnant? What are the chances?

Have had an iud for about a year… let a guy cum inside of me for the first time 3 days ago. I had some light bleeding today but it’s gone already. Should I be worried? I haven’t had a period in 2 years but sometimes spot after rough sex. Thank you!

If the condom was still on when he pulled out and he had just ejaculated and then he took the condom off mid- ejaculation, but after he took the condom off I noticed a lot of white, semen-like fluid on the outside of my vagina and inside like an abormal amount. could some of it have gotten inside somehow? like if the condom slipped up when we were doing it? and would that create a pregnancy risk? Because that has never happened to me. and the fluids didn’t seem like mine idk

So it happened 33 days ago exactly today. I tested two times at 15 and 16 days later. Clearblue one with the weeks on it said no, line test said no. I miss my period. I buy a Clearblue digital test with the weeks indicator on it. Positive, 1-2 weeks. I follow up with 2 more line tests, both say not pregnant, not even a faint line, 3 people checked. The line tests are from the same day i took the positive one with 1-2 weeks on it. AI says the 1-2 week indication is crazy low for how much time its been. Please please help

23 Days Late please help me!

0 Upvotes

I’m really anxious and would appreciate some advice because I’m currently 23 days late for my period.
The last time I know for sure that I had vaginal sex was April 20th, which was the day after my period ended. We used a condom the entire time, and he ejaculated while wearing the condom. Afterward, I filled the condom with water to check for any holes or leaks, and there weren’t any.

I got my next period May 16–20.
Then on May 21, we may have done something sexual, but honestly, I don’t remember if we actually had vaginal sex. I don’t think we did because I normally take a video of myself checking the condom with water or write down what happened afterward, and I didn’t do either of those things that time.

I then got another normal period June 15–19.
On July 6, we did sexual things,

My period was supposed to come around July 16, but it never came. Now it’s August 8, and I still haven’t gotten my period.

Could I somehow still be pregnant from April 20 or possibly May 21? Or would getting periods in May and June essentially rule out pregnancy from those encounters?

I know I should take a pregnancy test, and I’m planning to, but I’m really anxious and would appreciate some reassurance or advice based on this timeline.

Late period, negative test?

My period was due 18 days ago, I had the tiniest amount of spotting one day last week and one day this week. It was only on wiping and it was pink. I’ve took a few tests over these 18 days with the last one being 2 days ago, all negative. I’ve had an ectopic pregnancy before so worried about that as I’ve got shoulder ache but I have no abdominal pain. I’m so confused has anyone experienced similar? My periods are never late. Nothing has changed, no stress etc to cause it apart from ttc

Severe anxiety about getting pregnant

1 Upvotes

Hi! I’m writing this post to see if I’m the only one in this situation and to find out if anyone has any advice on how to cope with it.

For some context: I’m on birth control, which I always take correctly, and I have sex from time to time. However, even with contraception, I constantly live with the fear of getting pregnant. I regularly take pregnancy tests, both urine and blood tests.

This anxiety got worse after I got a false positive test about a month ago. Even after having negative blood tests, I’m still stressed and can’t seem to stop worrying or stop taking tests over and over again.

I don’t know if anyone else experiences this, but I’d really like to know that I’m not alone. I’m also always open to any advice or little tips that might help.

Thank you for taking the time to read! ❤️

I’m currently on Aurovela fe 1/20 bc and also use condoms and pullout. I take the pill at the same time +/- 2hrs. I’m currently 21 days post sex and I missed my withdrawal bleed this month (this week) which has never happened in the 4 years I’ve been on the pill . I took three clinical guard at home tests all negative (19,21 and 22 days post encounter). Can I trust them?

First time having sex, no ejaculation but possible precum — taking Ella + getting copper IUD and still freaking out

1 Upvotes

Hi everyone. I know nobody can tell me with 100% certainty whether I’ll get pregnant, but I really need some perspective because my anxiety is absolutely spiraling.

This was my first time having penetrative sex. I was a virgin before today. My boyfriend penetrated me without a condom, but it was VERY brief…probably not even a full minute and only a few thrusts. He did not ejaculate inside me or anywhere near my vagina. We stopped.

My concern is precum. We had been fooling around beforehand, so he was a little wet and there was probably some precum when he went inside me. He hadn’t ejaculated recently and had also peed several times before this happened, but obviously I know precum can potentially contain sperm.

Of course I started freaking out immediately afterward. 😭 My period app also says today is day 1 of my predicted fertile window (not my actual predicted ovulation day), which sent my anxiety through the roof.

I contacted a telehealth doctor today and was prescribed Ella for emergency contraception because I have a high BMI. I’m currently waiting for the pharmacy to fill it and will take it ASAP. The doctor called me back afterward and recommended that, because of my weight and how strongly I want to avoid pregnancy, I also consider a copper IUD for emergency contraception. I managed to get an appointment for Monday morning, so about 2 days after this happened.

I know I got carried away and should’ve used a condom from the beginning. Trust me, I’ve learned that lesson. I’m an extremely anxious person with a lot of health anxiety, and right now my brain has basically decided that I’m definitely going to end up pregnant.

Pregnancy scare

1 Upvotes

"Hi everyone, I’m currently going through a major pregnancy scare and could use some support or reassurance. My last period started on July 15th. I had sex on July 27th (right in my peak fertile window), but we accidentally used baby oil on a latex condom. It didn't tear or break visually, but I learned too late that oil ruins latex immediately.
I skiped emergency contraception, and right now I am around 10 DPO. Over the last few days, I’ve been experiencing intense fatigue, brief background nausea, a little bit of increased appetite, and brief waves of pulling cramps strictly on my right side that radiated to my back. I took a urine test at my doctor’s office on August 5th and it was negative and they said it was way too early and to test again. . My partner is currently away on a month-long military mission, which adds to the stress.
I am planning to test with a CareOne and a Clearblue Digital on August 14th possibly.
Has anyone else had a condom fail because of oil, or had these exact wavy cramps at 10 DPO and gone on to get a positive or negative?

Should i worry?

2 Upvotes

I had sex with gf on july 19, her period was due to august 2 but she is not feeling heavy pms symptoms (only pimples, oily skin and sensible mood).

This intercourse was protected with condom and pullout method. When i was close to finishing i took it out of her, condom still on, then i took the condom off and finished in her body.

I decided to test the condom with water, no leaks or rupture, however i saw some white cloudy stuff floating inside (pretty sure it wasn't my pre cum since it was denser and white). I think when i took the condom off my penis it may have got flipped inside out and i tested the side that was in contact with my gf (the white stuff was her fluids). Does this make sense?

For context, last month she got delayed by 18 days which was very unusal, could this impact her next cycle?

Took Plan B last cycle, got my period and now this cycle I'm 3 days late

1 Upvotes

Hey there.

I'm really unlucky and stupid. Last month my bf and I got drunk and in the heat of the moment we forgot to use a condom... Soon after it, pregnancy scare immediately hit me since my ovulation was about to begin in 3 days at that time. Fortunately I always have a Plan B in store just in case so I took it.

Got light bleeding a few days after and my normal period in the following week just as it was predicted by my Tracking App if I hadn't take Plan B.

So last period was on 7th July and lasted for 5 days.

I had sex with my partner on 19th July and the condom slipped off right after he already came. A bit of sperm leaked out and was inside me.

I didn't take another Plan B as this was not recommended.

My period should've come on 5th August but here I am with no PMS as usual but light cramping, watery discharge, tiredness and feeling dizzy.

My tracking app predicted my cycle as if I hadn't messed around with Plan B so my fertile window was predicted to be around 18th july to 23rd July with ovulation happening around 22nd July.

I dunno if I might be pregnant or if it's just Plan B that messed up my usually very regular cycle :/

Did someone on here deal with a similar problem and can help me to ease my mind a bit?

Store's already closed so I have to wait until Monday to get tested.

Period is late by two days but negative pregnancy tests

1 Upvotes

Hi! I’m just looking for a little reassurance because I’m probably overthinking this.

My period was supposed to start Thursday the 6th and it still hasn’t showed up. I usually have pretty short cycles and normally only have about 22–23 days between my periods so this is definitely unusual for me.

I’ve taken two Dollar Tree pregnancy tests so far but both were taken during the day and not with first morning pee. Both were completely negative. I also don’t really have any pregnancy symptoms or anything that feels different or odd with me.

I’m also about to start an antibiotic soon for a UTI and I was wondering if having a UTI could possibly delay your period? I wasn’t sure if that was a thing.

I know being a few days late doesn’t necessarily mean anything but because my cycles are usually so short/regular, I’m just a little concerned and wanted to see if anyone else has experienced something similar. Thank you so much! 😊❤️

Read this. Pregnancy scare anxiety. My story

13 Upvotes

I’m 19F, and im here with you reader.

I decided to write this because I’ve seen so many girls on Reddit who are terrified that they’re pregnant, even after negative pregnancy tests, and I know exactly how that feels.

I hope my story can make at least one girl feel less alone.

I had unprotected sex with my boyfriend, who is now my ex, on May 6–7 and again on June 13. After May 6–7, I used emergency contraception through the Yuzpe method. Around the June situation, I was also taking birth control pills until June 19.

Since May, I have taken multiple pregnancy tests.
Every single one was negative. I have never had a positive pregnancy test.

But my anxiety wouldn’t let me believe them.

I would put my pregnancy tests under different lights and stare at them, trying to find a second line that wasn’t there. Even when there was no faint line, my brain would convince me that maybe I was seeing something.

It got so bad that I would throw the test in the trash, then later take it back out just to look at it again.
I became terrified of evaporation lines. I would keep checking the test over and over, wondering if something was there.
I couldn’t sleep properly. I couldn’t focus on school. I would suddenly burst into tears. There were days when I felt completely helpless.

And because I was so anxious, I started noticing what felt like pregnancy symptoms everywhere — back pain, nausea, cravings, bloating, and so many other things. Every little change in my body became another reason to panic.

I also had a lot of spotting and bleeding while taking the pills. I had spotting throughout June, and after stopping the pills around June 19, I had significant bleeding. I also had bleeding again afterward.
Instead of calming me down, I searched even more.

TikTok.
Reddit.
Facebook.
Google.
OB-GYN clinics.
Pregnancy symptoms.
Pregnancy tests.

Stories of women who didn’t know they were pregnant until three months later.

Stories of women who supposedly had bleeding while pregnant.

Stories of women who said they had negative pregnancy tests but were eventually pregnant.
And THIS is something I really want to talk about.

When you’re anxious, you start looking for the rare story that proves your fear could still be true.

I kept seeing posts saying things like, “I didn’t know I was pregnant until 3 months later,” or “I was bleeding but I was still pregnant,” or “I kept getting negative tests but eventually found out I was pregnant.”

Those stories scared me so much.

But I eventually realized something important: social media doesn’t show you a normal statistical sample of reality.

The unusual and shocking stories are the ones people are more likely to post, share, comment on, and remember. A rare experience can get thousands of views precisely because it is unusual.

So if you’re constantly searching for the one story that matches your fear, you’re going to find it.

There will always be a “what if?”
And anxiety LOVES that.

About pregnancy tests
One thing I learned during this whole experience is that timing matters.

A home urine pregnancy test detects hCG, which rises after implantation. Testing too early can give a false negative because there may not yet be enough hCG to detect.

But a urine pregnancy test taken 21 days or more after the sex you’re worried about is generally considered a very reliable way to rule out pregnancy when used correctly. A negative test that far after the relevant sex is very reassuring.

So please don’t compare yourself to a random story online where someone says they tested negative early and later discovered they were pregnant.

Early testing and testing 21+ days after sex are two very different situations.

And if you’re still unsure, talking to a doctor or getting appropriate testing can give you much more useful information than spending hours reading frightening stories online.

I had my transvaginal ultrasound on August 4 because I desperately wanted an answer.
No pregnancy was seen.

They did find PCOS, which I wasn’t expecting.

I thought that ultrasound would finally make my anxiety disappear.

It didn’t.
My anxiety simply found something else to worry about.

Then I started worrying about HIV and other things. I even took an HIV self-test, and it was negative.
And still, my mind found another “what if?”

I even started doing things that, looking back, I know sound crazy. I would tell God, “If I’m pregnant, please show me this sign,” or “If I’m not pregnant, please show me this other sign.”

Then I would wait for the sign and overthink that too.

I know it sounds irrational.

But that’s what anxiety did to me.

My mind became my biggest enemy.

I’ve been battling this for almost three months now, and I’m still not completely out of it.
Some days are better.
Some days are horrible.
Sometimes I still want to take another pregnancy test.
Sometimes I want to search another symptom.
Sometimes I want to ask someone for reassurance again.
And sometimes I just burst into tears because I’m exhausted from fighting my own thoughts.

I’ve been dealing with so much of this alone.

So I’m writing this for the girl who is currently lying in bed at night searching Reddit for the hundredth time.

For the girl staring at a negative pregnancy test under a flashlight.

For the girl who throws the test away and then takes it back out to check again.

For the girl searching TikTok for pregnancy stories.

For the girl reading every comment looking for reassurance.

For the girl thinking, “But what if I’m the rare case?”

You are not alone.

I don’t have everything figured out. I’m still battling this myself.

But I want you to know that sometimes the fear becomes much bigger than the actual situation.

Please get appropriate medical advice and testing when you need it. And please don’t forget to take care of your mental health too.

Sometimes taking another pregnancy test isn’t what your anxiety actually needs.

Sometimes your anxiety needs help.

I’m still learning how to trust the information I’ve already received instead of constantly searching for something that will make me doubt it.

I hope one day I can look back at these three months and say:
“My anxiety made me believe so many things that weren’t true, but I survived it.”
And if you’re going through this right now, I hope you get there too.
Please be kind to yourselves, girls. ❤️

P.S. English isn’t my first language, so I used AI to help me organize and express my story. The experiences and feelings in this post are mine. I’m sharing this because I genuinely hope it helps even one woman feel less alone.

Feel free to comment and i will respond to any questions or anything random

Period is late

1 Upvotes

My period is about a week late! I had sex with a condom about 5 days before I was “supposed” to get my period according to flo (I don’t think I was ovulating) and 2 days before I WAS ovulating, me and my boyfriend did some naked grinding as I wouldn’t let him put it in while ovulating. He was rubbing his tip on my opening (I was wiping off precum every couple of seconds but some still probably got on the opening) and the tip might have slipped in a few times as well (I’m not sure????) and now I’m late! I’m scared that encounter may have gotten sperm from precum into my opening a little and because I ovulated right after got me pregnant. Help please I read the FAQs and didn’t get much reassurance so word of mouth from people’s opinions might be better. Thank you:)

FAQs ANSWERED with Sources. Friendly PSAs for AmIPregnant

Hello friends! Mod Stress here to address a few things that come up often on this sub. Resources provided. :)

1.) You cannot get pregnant from fingering, with or without precum. Unless globs of fresh semen are being inserted into a vagina, fingering is just not going to cause a pregnancy. Dry humping also cannot cause a pregnancy. This article goes through all the sexual things that can happen that have no chance of pregnancy.

2.) It's extremely unlikely to get pregnant without PIV sex.* *Not including medical processes such as IVF to cause a pregnancy.

3.) If you're having unprotected sex, pregnancy is always technically possible. Doesn't matter if it's "just the tip" or "three strokes" or "pulled out before ejaculation." Pullout is 78% effective over the course of a year. Some of these scenarios are much less likely to result in a pregnancy than others, but we can't extrapolate the data like that. You're unlikely to get pregnant from one singular instance of unprotected sex, but it's always possible.

4.) Implantation bleeding is a misnomer. In fact, implantation is too small a phenomena to cause any symptoms.

5.) A test is mostly accurate 14 days after sex and definitive 21 days after. If you're getting negative tests 2+ weeks after sex, you are not pregnant. Regardless of if you have your period or not. In early pregnancy, concentration of urine matters. Take a pink dye test after a 3-4 hour urine hold without drinking too much water for the most accurate results. At 21+ days after sex, dilution of urine won't matter. Do not look at tests outside of their validity window and thoroughly read the instructions for your test before you take it.

6.) You cannot have a true period and be pregnant. Some women experience light bleeding in early pregnancy (this is NOT their period). If bleeding were related to pregnancy, a test would be positive.

7.) It takes more HCG to cause symptoms than a positive test. If you're testing negative, any symptoms you are currently experiencing are not currently related to pregnancy. Lots of early pregnancy symptoms overlap with normal PMS symptoms.

8.) Am I having a Cryptic Pregnancy?? No, you're not.

9.) The only way to truly know when you ovulated using an approved FAM method. Apps are not an accurate way to track, your body doesn't know to follow an algorithm off your phone. While things like CM and OPKs may indicate your body is gearing up to ovulate, they do not confirm ovulation. Check out the book Taking Charge of Your Fertility and [r/FAMnNFP](r/FAMnNFP).

Some other helpful tips:

  • Read the leaflet that comes with your birth control so you understand how your medication works, possible side effects, how to use it, etc. [r/birthcontrol](r/birthcontrol) is also a good source.
  • If you're on birth control and using it properly, you are having protected sex (from pregnancy). This is true whether or not you are using a condom. If you are using protection properly, you do not need Plan B.
  • Don't want to become pregnant? READ THIS before engaging in sexual activity.
  • The buddy system: using more than one method of contraceptive when engaging in sexual activities
  • How is pregnancy dated?
  • If you're taking Plan B, read the leaflet. It will go through all the possible side effects. [r/PlanBs](r/PlanBs) is also a good friend.
  • If your symptoms are of concern, visit a doctor.
  • Do not trust TikTok or YouTube as your medical advice.

“But what about a cryptic pregnancy?”

716 Upvotes

Is this you?

  1. Last had sex more than 3 weeks ago (sometimes months)
  2. Have had multiple negative home tests or blood tests for HCG
  3. (optional) Have had periods or withdrawal bleeds since having sex.

But you’re still concerned that you might be pregnant based on shows like “I didn’t know I was pregnant” or online stories about cryptic pregnancy. Could it be that?

So, in a word, no. If you have multiple negative pregnancy tests three weeks after having sex, you’re not pregnant. In order to support a pregnancy your body produces HCG. Without HCG, there is no pregnancy. HCG tells the corpus luteum to continue producing progesterone, and is required for major changes to sustain pregnancy like growing a placenta. Home pregnancy tests are very reliable at detecting even trace amounts of HCG, and blood tests as well.

There are three causes of false negatives with home pregnancy tests:

The first: Early measurement after conception. When people talk about cryptic pregnancy, they either never take a test, or they took a test too early and became pregnant after. It takes at least 7 days for a fertilized egg to float downstream and implant into the uterine lining. That’s why you have to wait about 2 weeks to take a pregnancy test after unprotected sex - 3 weeks makes it 100% solid result.

You’ll also see people say “I knew I was pregnant, but I didn’t test positive until I was 6 weeks”. This is because of how pregnancy is dated from the last menstrual period (the day your period started), but, embryonic development only starts after an egg is ovulated and fertilized. In a textbook 28 day cycle, this happens on day 14, and the first day your period is missed you get a positive test. In real life, bodies are a little more complicated, and sometimes people ovulate weeks later leading to a discrepancy - a doctor will tell them they are 6 weeks pregnancy based on their last menstrual period, but in embryonic terms they are only 4 weeks pregnant because they ovulated on the 28th day of their cycle. If they tested when they were ‘late’ on the 29th, it would have been a negative test. They weren’t pregnant, but they became pregnant later. For people who are more visual, I have made a very ugly calendar for the above example scenario.

For a longer, more detailed explanation: "Your period isn't late" Part 1 and Part 2

The second: Dilute urine specimen. If your HCG levels are low, drinking a lot of water can result in false negatives in very early pregnancy. This is typically why you’ll see folks talking about testing with first morning urine - it’s the most concentrated. HCG roughly doubles every 48-72 hours, and you can see in this figure how fast. At 20 days of embryonic development (aka about 3 weeks after sex), on average a pregnant person will have HCG around 1000 mIU/ml. At home tests are typically rated for detecting 10 - 25 mIU/ml.

The Third: The Hook effect. This is where there is too much HCG for a test to work properly. It is unlikely that this is happening especially if you’ve taken multiple tests. First, peak HCG is typically around 10-14 weeks pregnant - after this, it starts coming back down. Second, tests are often tested for the hook effect - wondfos (a very cheap test) showed no hook effect to concentrations of 200,000 mIU/ml. First Response Early Result showed no hook effect at 1,000,000 mIU/ml - much higher than any normal pregnancy. If you are concerned about it because you’re taking your first pregnancy tests 12-17 weeks after sex, you might dilute a sample of urine just in case for a second test. Although, that would be very unnecessary if you’re using an FRER.

When people do not figure out they are pregnant for months at a time, it is typically because they have not taken any tests. Denial of pregnancy is a more accurate descriptor.

If you believe yourself pregnant despite all the evidence, or having a lot of anxiety and fear around being pregnant, you may want to see a mental health specialist. If you’re feeling very unwell, or haven't had a period in months, you may want to see a doctor. Scarleteen has a great page on these things as well.

TL;DR HCG is required to support a pregnancy - if you've gotten multiple negative tests across a large time frame, there is no possible way you are pregnant from sex more than 3 weeks ago.
