... week and a half away from my period. I started inexplicable bleeding three days ago, and it has gotten heavier. It feels like I have menstral cramps, even though this isn't menstration. I am not sexually active (nor have I been) and I'm wondering if this heavy bleeding is a serious problem that I should seek a doctor's oppinion on. And if I do need to seek out my doctor, how soon do I need to do it? (And/Or) How serious IS this?
