Today is the 18th of August. Ive been on birth control for over a month now. I quit taking it for a few months and started back on it just last month but when I went to go get my prescription, I waited a week or a little longer and I didn't have my period. As soon as I got my other prescription for my birth control, I started taking it the first day I got it which was Tuesday the 7th. On the 11th, I had unprotected sex with my boyfriend and I was on top. We thought the gravity effect would come into play (what goes up, must come down) and when he got off, he wasn't in all the way. When I got off and cleaned up, it looked like mostly everything came back out. But I used the restroom a little bit ago and I wiped and had brown bloody discharge? I've been feeling a little different lately. Earlier today I just felt sick to my stomach and gained a little weight it feels like. We've had sex since the 11th but he pulled out. I'm scared I could be pregnant. Please help me out with feedback. I'm stressing out beyond belief.
