I'm 14 years old and I've been on my period for three weeks now. This hasn't happened to me before. I'm usually regular. I'm not on birth control. And I am still a virgin, so I'm not sexually active. What do I do? Its scaring me. Is it bad? Help. :(

It can be normal to have irregular periods in the first few years of having them, but since it has been going on for a few weeks, it would be a good idea to see your doctor about it.
