I'm 18 turning 19 in a few days and I just lost my virginity to my boyfriend less than a week ago. We didn't use protection but he pulled out early. And I'm waiting any day to get my period any day now because people say it won't effect this cycle but idk I've been really paranoid and scared that I might be pregnant. I may just be over thinking things but I can't have a baby right now. I'm not ready! And should I go on actual birth control pills? I just don't want it to effect my chances of getting pregnant later in life
