i was supposed to start my period on thursday. it’s now 4 days late. (it’s usually a little late but not almost 5 days late). i just started BC for the first time on sunday. and now i’m cramping so badly. like right near my belly button. i’m so scared that i’m pregnant. is there a chance that i am or is it just the BC acting with it? my boyfriend and i did have unprotected sex for like 2 minutes but that’s it
