My period never stops

Aleta T. • ♍️

Guys, For the past two years I’ve been having my period for two and a half weeks at a time or more and I can not begin to tell you how sick I am of it. It will not stop and I have no idea what to do. I have seen my OBGYN a million times for this issue and I’m exhausted because NOTHING has worked. I’ve tried six different birth controls and nothing will make my period stop. I need serious help because I can’t take this anymore. Does anyone know what could be wrong?
