Me and my boyfriend had unprotected sex 4 weeks ago, at first we were just kissing and he was touching me and I was "riding" him I guess you could say but We had our clothes on after I went to roll over and took our clothes off and my hand touched him it felt a little wet I don't know if it was precum or cum or if I just thought it was but I didn't say anything we just kept kissing and he put a condom on and put it in for bout 30 seconds then took it off and put it back in for around 5 minutes we ended up stopping but I don't think he cumed or precumed but at the same time I think he did, I'm not really sure I haven't talked to him about any of this.. ever since that happened I had a feeling I was pregnant, a day or two later I had my period for 1 day but it was nothing like a period at all and it was my time, iv been feeling nauseous having really bad headaches a little bloated, and today I just started my period and it's around my time, but I still feel nauseous bloated sore breasts bad headaches I just have that feeling I'm pregnant, sorry if I told to much detail I just really need to know! Is it even possible?? Could I actual be pregnant from this??
