I also went through early meno at 38. I started on Oestrogel, 2 pumps a day plus 100mg of Utrogestan, used vaginally for 10 days per month,which is the Progesterone part of the HRT, I searched for months before finding it as I was wanting something as natural as possible but was told by my gynaecologist to stay away from the creams as they are not strong enough.
I have never looked back.
Using a transdermal HRT is considered much safer and Utrogestan as well as the gel are bio identical hormones, you need HRT not only for another 5 yrs but until you are at least into your 50s which I am now, and after seeing my gynae 2 weeks back and him telling me that he still has ladies in their 70s and 80s using it, I do not intend to give it up. You are doing yourself an injustice at such a young age by not topping up what your body should naturally be processing, I can highly recommend the gel, or the patches with a separate Progesterone, you will still get a monthly bleed on this regime. All the best, its a horrible diagnosis, but not the end of the world, lots of support and assistance here.
