I really need some answers. I haven't had a period for 62 days and started hrt - I started the gel for two weeks then then I'll move on to the progesterone. My panic is my doctor told me I should have started the estrogen and progesterone together to avoid a the thickening of the lining of my womb. What damage have I done by taking the oestrogen on it's own for a week? any advice really welcome as I couldn't get much sense out of my doctor! Do I start the progesterone straight away for the two weeks or do I wait another week?
