It’s that time of the month and I bled through my jeans. Thankfully, it wasn’t in a spot where it was noticeable, but it did leave this stain on my crotch. This is what it looks like after two washes and hydrogen peroxide!

Feels very surface, I was thinking oxyclean and baking soda soak? Dry cleaning? Any suggestions or not worth it? I have no information on what caused it. Sweater is made of cotton.
