i have a question. My boyfriend and i are in a long distance relationship because he's in the military. i saw him in august of this year and had just gotten over my period. well, after a week of being sexually active, i came home. after that, for 3 mos i didn't have my period. i took tests but came out negative. could it have been because they were the cheap brand? anyway, when i went to see him again this nov. i was there for 2 weeks. my first week nothing. then, i started lightly spotting 2 days prior to me leaving, i began to bleed a river but then stopped and started back up again. so, I'd say about another week before it completely stopped bleeding. but since then, i've been spotting almost daily. What could it be? i'm worried. I've never had this happen to me before.
