I want to know why I've been on my cycle for two monthes?

This is like asking why my car won't start, and not allowing someone to look at the car.

You go to the doctor and get an exam and find out why. There are 1000's of possible reasons, and no way to know what issue is yours.

You need to go to the doctor. It could be nothing. My periods would skip months and then I would have a period for a month at a time. For no reason.

It could also be something more serious. And there is NO way to know online. Good luck!
