I'm a college student and I've been stressed to the point of no return the last few weeks because of midterms. I had sex with my boyfriend on Valentine's Day and we didn't use protection,  he pulled out. I take my pill everyday at the same and have been on for about a year and a half. My period has been on point the last two months and im starting to freak about being it not arriving. I haven't had any symptoms...yet.
