Hi Gilla, thanks so much for replying.I know what you’re saying, totally, but I think I’m quite in tune with my mind and body so I’m pretty confident when I think something is due to low oestrogen. Also I got an anterior prolapse when I was in my late thirties which I understand is due to falling oestrogen. Every month I seem to have two good weeks where I can feel good positive etc and two challenging weeks where I’m tired, sometimes exhausted, can’t feel good, negative, etc, and it’s definitely cyclical, but the bad period is getting longer and the good period shorter which all points to oestrogen. Im going to increase to 3 pumps and just see what happens. I have spoken to my gp and she suggested increasing the dose, she believes women usually know what they need and can increase if necessary. I agree, I tried stopping HRT at one point due to utrogestan related issues and I got terrible withdraw symptoms after 9 days which another gp says were just my symptoms returning, but it felt different. Anyway I’ve resolved the utrogestan issues. Can I ask what issues you had due to high oestrogen and how did you know they were due to high oestrogen? That’s a really great idea about measuring half a pump. Being in a similar position to you I’m very interested in your experiences and may PM you at some point if that is ok?
