So I'm new to this site but I need some advice. My boyfriend and I are sexually active. Use protection more often than not and never ejaculates inside or near my vagina. My periods 3 weeks late. When I should have gotten my period I spotted a light brownish pink for a day with horrible cramps. I'm nervous... I'm only 18, my boyfriend is 23 and were both still in school. I've taken one negative test.
