I lost my virginity on the 2nd of October 2009. In feburary 2010 I noticed pain in my uterus normally the left ovary. Ive had ultrasounds and they sorta narrowed it down to mittleshimerz but not a definite. Then I didn't have pain for a couple of months later until July/September. I'm kinda paranoid that it could be an std. I haven't been active since that date.
