I had unprocted sex with my boyfriend a week ago and I was supposed to start my period 6 days ago, so we had sex a few days before I was supposed to start my period. He said he might have came in me, Ive had pregnancy scares before and he was never worried but now he's worried and im less worried because I don't want to stress about it. My boobs hurt really bad too, but that could be because I'm PMSing. What do you think?
