This is all very interesting...I have had the Mirenea coil fitted back (again...had it for birth control and to control bleeding but then after my 4th one doctor took it out and said I was too old...early 50s ..to have another one. ) I had to fight to have it back but utrogestone wasn't really right for me and I kept having breakthrough bleeds...not nice for me and expensive for the NHS as each time meant a scan at the hospital...and my womb linging was up an down...or rather thicker and thinner!
I am on Estrodot...which since increasing to 50 (which worries me..is that a big dose?) and having the coil I have had no breakthrough bleeding really. I was a little worried that the coil would protect me as much as utrogeston but the consultant..who wasn't a meno specialist but a gynae one...assured me it would. I do wonder how long for tho....
