Is there anything that i can do at home to help control/stop my heavy menstral cycles? i can't take bc pills because i've have breast cancer before...

Need a gynecologist: Unfortunately, there is little that you can do if you have excessively heavy menstrual periods. If you are sure that you are done having children, there is a newer minimally invasive procedure that involves placing a balloon inside the uterus, and heating water in the balloon to destroy the uterus' inner lining. No lining = no/minimal periods. See a gynecologist. If you take Tamoxifen, go NOW!
