I had unprotected sex almost 3 weeks ago. My boyfriend urinated about 15 minutes before we had sex (I was informed urine kills sperm). We literally had sex for 30 seconds and we kept pulling out to wipe. Then he pulled out early before he came. Ever sinced that day I've been regretting ever doing it, and I've been so stressed that I might be pregnant. I cry everyday just thinking about it... That's how stressed I am. My period is due today. But it hasn't come yet. My period is never on time. I have no symptoms of my period or pregnancy. The only thing is minor lower pelvic pain, it lasts for about 30 minutes. It doesn't hurt at all. But I am freaking out! I feel totally normal. I have strep throat right now idk if that has anything to do with my problem. Please anybody any answer is greatly appreciated.
