My period came about the time it usually does. Then, after a week, when it's supposed to stop, it hasn't. It's been two weeks and I'm still bleeding. It's a heavy flow. But last month, I didn't get my period. Later this week, I'm going to on a trip, and I don't want this to ruin it. Is there a reason why it hasn't stopped? I'm really scared. Could it be from my sudden stop of exercising.. Because track ended. I don't know what to do. It becomes very light for a few hours and then it just becomes heavy again. At night, it's the worst. I get so many blood cots. This has never happened to me before. I am not sexually active. If you could help with this, that'd be great. Thanks!
