Hi, I had a lot of bleeding and blood clots that was A LOT so my gyno did an endometrial biopsy and then told me i have complex hyperplasia with atypia and i need to go to a gyno oncologist......my medical history is i have been on klonopin for anxiety and insomnia for 14 years and i know that the klonopin has caused me a lot of health issues and i believe this could be because after the fifth year of klonopin use i just stopped having my period and i was in my early 30's and i have talked to other women who take klonopin long term who also stopped having their period as well......so if the thicker lining is causing the huge blood clots to come out.......is there a chance that i should have a second opinion biopsy or would not having your period for so many years cause pre-cancerous tissue?
