Hi, ok well I'm 18 and I have been sexually active with my boyfriend of a year for like 2 months now. I was supposed to get my period 2 weeks ago, and I'm usually regular right. But the day before my period. We had Protected sex and the day of my missed period unprotected sex, he pulled out everytime he was going to ejjaculate, and I know about preejaculation.. But I thought that my period would come, so I waited.. Its now 2 weeks, and we had sex like 4 days in a row, unprotected... 2 days after he left I started what seemed like my period but it was very light. And ended after one day and only shows up when I wipe... I had cramps, lowerback pains, tender breasts headaches and fatigue... still doo, nd some abdominal pains... what does this man?
