Hi and welcome to MM flower1
You've had a tough time - you poor thing. Major surgery is no joke and I can understand your concerns. We are here to support you, so do share your experiences. Hopefully your doctors will prescribe a good HRT for you post op, as at your age you need HRt to protect your heart and bones for the long term and also prevent urogenital atrophy.
Read up all the info on this site to get clued up. Print off the different HRTs under TREATMENTS above so you can discuss your options with the doctors. It can be good to start with a sequential HRt and put up with a monthly bleed - this allows you to assess whether the progesterone in a particular HRT type suits you or not. It can be good to start with Femoston. They might offer you a Mirena which can be a good option as you simply add oestrogen as a patch or gel alongside.
Going into surgical menopause can be tough at first but if you are prepared and given HRT straight off, this can prevent the meno symptoms emerging too strongly.
Good luck. DG x
