So husband and I had sex last week and I didnt realize I ovulated that same day. I know he didnt cum inside of me but on top of me. We are not preventing it from happening but just kinda doing whatever. But now its a week after - 7 days post ovulation and Im extremely nauseated and I was in so much pelvic pain earlier that I was hunching over. Not sure if maybe im just getting sick or if I could have accidentally gotten pregnant. I know precum is possible but isnt that like a 5% chance? Idk I think its all in my head and needed to rant. Guess we'll find out next week if its all in my head or not when AF comes (or not?) 😅
