I need help.. I'm 17 years old.. I've been with my boyfriend for over a year .. well july 3rd to july 5th I had a period. The next tuesday (4days later) we had unprotected sex. About 2 weeks later I stated bleeding. I didn't think anything of it. The first day was heavy thw second day was fant and spotting. The third day was mucusy . I was supposed to start August 3rd. Its now the 28th and I haven't even spotted. I've been cramping for about two weeks and I feel like I've started. When I wipe its gooey and has a strong smell.. I took a test and it was negative but I want some advice from some ladies that know something about my problem. Any suggestion? !?
