Thank you both for replying.
Prior to hrt the gap between my periods had gradually increased. Bleeds were light, dark brown and full of clots. Sometimes skipping a month or two. It was impossible to predict. And then nothing for about 6 months before I started hrt. By which point I had full on hot sweats, migraines, mood changes, brain fog and vaginal atrophy. And I was finally diagnosed.
I suspect this began 7 years ago so maybe i am entering the post menopausal zone.
I take the progesterone orally and generally feel pretty well (although who remembers what normal feels like any more!).
It's good to know there is scope to increase my oestrogen. Although I may well wait until the hrt shortage clears up. I have gathered a little supply and don't want to complicate things any further.
It's all such a minefield and almost impossible to get an opportunity to talk things over with my GP. So I really appreciate your advice thank you xx
