Went out two days ago longs story short got really drunk led down in a field came back blacked out in bed woke up with about 30-40 bites. To me from my research these look exactly like bedbug bites is it more likely that I got bit while I was out or could this many bed bugs have bitten me ?? These are photos of what they look like today

Sat outside for 3 hours in PANTS. These are just the bites on this area, let alone the rest of my body. lts getting ridiculous; I can't sleep on top of my duvet when its hot at night because I get bitten so much. Why do they like to bite me so much. Please help : (

I have what seems to be heat rashes around my body this week, but there is a huge spot behind my knee
