So I have unprotected sex with my boyfriend (I’m on birth control) he pulls out I don’t know how long we’ve been doing that. But this week I was three days late on my period so because I was bleeding I started to wonder if I was pregnant and I haven’t took a test but we had sex on the third day of my being late and I got really bad cramps during it (like period cramps) and then this morning I started bleeding like nothing was wrong. But I remember reading somewhere that if you have sex before your period that you normally start to bleed then or early or something like that. So Idk what to do like if I should just not worry about it or if I should go get tested.
