About a year ago, I was told that I have PCOS. I was on MetFormin for awhile then had some life changes and just couldn t do the medicine at that time. I will be starting the MetFormin again soon. I ve seen a reproductive endocrinologist and they prescribed Zovia to help clear up my skin and regulate my periods. I ve been taking Zovia for 11 days and have been bleeding every day. Today, it s been alternating between bright red and dark brown. I also passed a blood clot the size of a half dollar today. I m wondering if there is a much better pill to be taking.
