Hi
in agreement with Hurdity.
"as I was having 3 periods in 28 days on femoston 1/10"
This is abnormal bleeding and should be investigated further. Don't panic but your doc should get this looked into.
To dump you into medium dose option without much more checks is not good.
This amount of bleeding is the cause of your anemia.
To not have iron tablets at the moment would be remiss.
Anemia has all sorts of knock on effects that you really dont want.
"i'm having withdrawal symptoms. Headaches, nervousness, insomnia and sweats"
This is just menopause symptoms and the hrt will take those away. Until you get further progress with your doc then keep with them to keep you more comfortable and rested.
Until you get doc you could go out and buy a multivit with iron in it just to try and help you build yourself back again.
