Hi Suzanne1967 - welcome to MM
Why anti HRT? It's the best treatment for early menopause to prevent osteoporosis and heart disease. If you are still working the flushes and lack of sleep can be crippling so staying on HRT till at least the natural age of meno, which is 53-54, is very sensible and continuing till 60 and then reassessing might be wise. I do hope you haven't been listening to all the scare stories in the press and from well meaning friends?
Are you on Elleste Duet conti? If so, then it is not unusual to get some bleeding on a conti HRT and this does need to be investigated but this should not mean you need to stop the HRT. If a scan showed some thickening of the womb lining or possibly a fibroid or polyp then treatment can be given to sort this. I hope you've been told it is highly unlikely to be anything sinister?
The sudden withdrawal of oestrogen will make you feel awful - you poor thing. I'd check whether you can simply start the HRT again.
I would possibly consider having a Mirena fitted after they have done the investigations as this will protect the womb lining better, it will often shrink and prevent polyps and fibroids, and you can simply use oestrogen as gel or patch separately to keep all the horrid meno symptoms under control and protect your health so you can keep working and enjoying life.
As a nurse you have a busy and stressful time so being on top of your game is important. Try not to worry, have your investigations and get back on some HRT as soon as possible - ask about the Mirena with separate oestrogen - here is the link about this on this site - the info about the Mirena is at the bottom of the page:
