My period came about 17th of September and it has not stopped. I still have it today 5th of October I have no pain or cramps with this period. It is very frustrating because I am trying to conceive.. Please help me,I don't know what else to do and I have tried birth control but all it does is shut down my reproductive system and makes me fat.

This is going to sound really condescending, but its honest advice. If you have been bleeding for over three weeks, you see a doctor. Sooner, not later.
