I am also 55, and have been taking the continuous regime. As sheila99 says you can get bleeding for the first 6 months. My bleeding started after 6 months, and ended up having a scan, like yourself the womb lining was fine and had a few fibroids but nothing to be concerned about. I continued on the same HRT, and things settled. Then the bleeding started again, and after a phone call with the GP, I was moved onto a lower dose HRT, Femoston Conti 1mg/5mg, the bleeding stopped. For myself, dropping down to a lower dose of continuous HRT worked, I am sure the GP said too much progesterone sometimes causes a build up of the womb lining, causing bleeding. It does cause some worry when the bleeding continues, plus its very tiring, and yes sends the hormones all over the place. Maybe a change of Conti might help things. Hope everything gets sorted at your appointment, and let us all know how it goes
