So about a week ago me and my boyfriend had sex...kinda. It was experimental and we used a condom and he even came outside of me and we didn't really get hat into it... A couple of days ago, on Monday, we did it again and so that means I lost my virginity. The thing is I was supposed to get my period two days ago and I still haven't and now it's Thursday. I'm about 2/3 days late. I've been having all of the period symptoms just no period. Is this anything to worry about or could it just be stress and the fact that I just had sex? I have no idea what I'd do if I was pregnant..
