I've just stopped using them. It was a very weird eperience. Bottom line -- I started having pains in my legs which signaled thrombosis. There are studies that transdermal estrogen can increase this risk. I tried lowering the dosage and started getting hot flashes - where I had none before. I then tried the normal dosage, but reduced the number of days used. Problem improved, but was never completely went away.

Doc is switching me to birth control pills (which I have used sucessfully before, with no problems) hopefully will get the benefit of them.
