I’ve switched to continuous as had the same issues and had been on it a year.
But then needed to increase oestrogen, which has led to erratic bleeds, or rather heavy spotting. I then moved to 200 daily and I am doing the 25/28 and it seemed to sync but then covid messed things up. So still seeing how things go. 25 was my suggestion; Gp was happy for just continuous.
There’s a 21 / 28 day regime (basically and extended cyclical regime) that I’ve read on the BMS progesterone sheet. If things don’t settle I may try this. Or mirena.
One of the reasons I wanted to try continuous was that I couldn’t deal with the ups and downs and terrible pms. I’m also on thyroxine and I just feel I need stability. It’s mostly really helped.
though this post covid irratic spotting has been hard work as I felt very faint with it too.
As witb all things hrt you have to give it a good 3-6 month trial.
