Period sex/ strange bodily functions
This past weekend my boyfriend and I had sex while I was on my period. I found a couple sites online that said the chances of pregnancy are very low, and I take birth control (I was on the placebos), so he came inside of me.
My period stopped about 2 days ago, but today...blood. Bright red.
My stomach doesn't hurt, but I have been a bit constipated for about a week (before we had sex.) I don't know if those are related.
I'm worried, I know my body well and it's acting so strangely.
