I am on Provera and have to take it every three months to have a period because of PCOS. Well I took it starting September 1st. 10mg twice a day. Well, I started on the 17th and still going. It's the 10th day! Ugh!!!! I've not had this happen like this. Usually it's 4-5 days of heavy bleeding and severe cramps. This period has been one day it's heavy and the next spotting and over and over again with severe cramps. Should I call my GYN today and ask her if its normal or do any of you know if it is or not? Please help. Thanks.
