Hello and welcome to EmpowHer,
There are many possible reasons to have frequent bleeding which can include:
--ovarian fibroids, cysts, or polys
--sexually transmitted infections
--thyroid problems
--birth control pills or IUD's

I have posted a link below that is a HERArticle which lists more possible reasons.

You should also see a gynecologist. Most doctors proscribe birth control pills if it is caused by hormonal imbalances and not any other serious reproductive issues.
