So on Tuesday, 4 days ago, I had unprotected sex with my boyfriend, he pulled out and came but then went back in pretty much right after. He didn’t clean himself off or anything. I’m pretty underweight but my period is normal. Because of my weight I just assume I can’t get pregnant. I don’t know why but I just feel like I can’t. Of course i don’t know for sure though. I’m supposed to get my period in 3 days. I don’t know if I should be worried or not? Is it even possible for me to get pregnant being so thin? I’m 19, and weight about 85lbs...

Please let me know your thoughts!!

Edit: I don’t feel or think I’m pregnant already, I’m just wondering if there’s any chance i could be
