So me and my bf had unprotected sex while i was ovulating about a month or so ago and he didn't cum in me and made sure all precum was gone before we had sex and it was quick. I'm now 13 days late for my period my boobs are sore  I have been cramping some and about 2-3 weeks ago I spotted for 2 days. I'm terrified I'm pregnant. ADVICE PLEASE!!!!
