Hello, I Have Been Given Nortisterone For Very Heavy Non

Hello, I have been given nortisterone for very heavy non stop bleeding with clotting (which stopped for a couple of years and came back 4 weeks ago. Initially it started in 2011. I had my only child in 2009 and I am Caucasian and 45, I have been cleared by a smear test but think it could be womb cancer and the bleeding is so bad I am now thinking a hysterectomy is the only answer. I also have a large fibroid in the uterus which is in a tricky place to remove. It's making me very tired. Thank you for any assistance you may be able to give. Larissa
