Help..

Ok, so I've been having issues with my cycles. I bled Oct 2-9 then again on October 19 and am STILL bleeding as of today, November 28. That being said. I've been to the Dr, got put on hormone pills, had a sonogram found out my uterine lining is a little thicker than it should be, so they did a biopsy to make sure it wasn't Cancer. Good news, it's not. Annoying news, they don't know what the issue is. I stopped the hormone pill on Tuesday. Dr said give it a week, and see if I'm still bleeding. And to start taking prenatals to hopefully have my body ready if it gets back to a regular cycle. Has anyone else has this happen? What was the outcome??
