Ok so Im 15 and I lost my virginity 2/3 weeks ago and lately Ive been getting small cramps on my body.I keep thinking I'm pregnant but when Im in school or out with my friends,my body is fine.all the cramping happens when I go to sleep at night because I think and stress too much. My bfs older sister keeps telling me that since my cherry was popped,my body is changing and my period will change too.I took two of the best pregnancy tests and they both said -no,but my body is acting has some symptoms of being pregnant and Im not sure weather its stress or Im really pregnant.the month just began and I haven't gotten my period yet and I don't know when Im gooing to get it and I used protection.any thoughts?

I don't think you would be having pregnancy symptoms this early.

Listen to the older sister, and listen to this too: most birth control has a pretty high failure rate except for the pill, patch, tubal, or abstinance. I think the failure rate of condoms is 25 - 29%.
