Hey everyone, I'm kinda new to this and I've just got a really weird question and I think I might be a little bit paranoid about it so no judging. Basically I had unprotected sex a week before my period came and then I got my period on time and it was like any other period except ever since then I've been gettin cramps and feeling like I'm gonna be sick and feeling bubbly in my stomach and everything and I am just wondering what it could be?? Like is it possible that I could be pregnant even when my period came on time and was perfectly normal?? I don't know if it's just me being paranoid or what but I'm kind of freaking out so advice or explanations would be great.
