Hi and welcome to MM Tina41
I'm afraid premature menopause is far more common than people think. My meno started in my mid 30s - I'm now 61 ( so used HRT for around 25 years) and only stopped HRT 18 months ago. You need HRT to protect your heart and bones for the long term and to also prevent urogenital atrophy. Don't let any doctor take you off HRT until you are at least 52-54 when would normally become menopausal. Many women continue HRT well into later life to gain full benefit.
Do read up all the factual info on this site to get clued up - unfortunately nobody educates we women about menopause so the effects can be alarming, upsetting and sometimes frightening. This site is great for getting you through.
It is an emotional shock to find yourself into meno too early and the lack of oestrogen can mess with the brain and emotions as well. Once the oestrogen works it's magic you may feel better.
If you still have your uterus you will need a combined HRT regime with progesterone so I hope the gynae/GP have given you progesterone alongside the oestrogen? At this stage they could simply have given you an HRT that had both - I'm baffked as to why they only gave you oestrogen especially as you have had fibroids? Perhaps you have a Mirena in place ? The Mirena is good for preventing fibroids ( fibroids often occur in peri meno, I believe, due to the lack of ovulation).
You say you ‘wanted another child', so do you already have children? I had fortunately had 2 babies, a girl and a boy, when my meno hit but I hoped to perhaps have a ‘luxury baby' in my later 30s - however, my son turned out to have special needs and having a baby when older does bring increased risks on many levels so feel another baby probably wouldn't have been a good idea.
Do look at another site that is for POF - daisynetwork - the link is on this site somewhere.
Keep us posted on your progress. DG x
