There's some good information within the Menopause Matters website to give you some basic information on what HRT is and the different options available. Click on the 'Home' tab and then 'What can I do about it.' (Or words to that effect, I've just checked there to find the right info for you and have already forgotten the wording 🙄) Have a browse around to get acquainted with the possibilities so that you can go into your Dr with a specific request.
A lot of us start off on Oestrogen Gel or on Oestrogen patches and those of us with a womb also need progesterone, generally taken in tablet form as Utrogestan. You'll see from the numerous threads within the forum that it can sometimes take a while to settle on a dose to suit you or, like me, you might be lucky from the get go and find your stable point pretty quickly.
Good luck with your appt
