So I had sex with my boyfriend while I was fertile and he came inside of me, I’m on birth control so I didn’t take a plan b and I know bc isn’t 100% effective. I’ve taken 2 pregnancy test and they were both negative and today I started bleeding but it is super light almost a pink color and I had what looked like a seed/ blood clot and it was round and the size of a pea. (That’s the best way I can describe it) does anyone know what this was? Was I pregnant and my body rejected it? I’m confused.
