About a month or so before Christmas, I was having sharp pains on my right lower side of my body,, like on my hip. I didn't take it to heart, but it hurt so bad I couldn't sit down comfortably. Then about a week before Christmas, I lost my virginity.. it was unprotected. He didn't ejaculate inside me though.. Because it was unprotected, he pulled out a little bit before he got close to ejaculating but I do understand he could have precame... A day after Christmas, it started hurting to pee and burned very badly.. At first my sister and mother said it was a bladder infection but I took medicine to treat it for about 4 days and nothing changed. Its only getting worse. I now have a bulge on the right side of my lower back and sharp pains around my lower stomach, almost feels like cramps when I'm on my period but I had my period a day after I lost my virginity.. Soo I'm not supposed to start for another 2 weeks! The burning sensation when I pee is still continuing.. Anyone know what it might be? Does it have something to do with my kidney? Appendicitis? Hernia? Pregnant? Please answer ASAP!
