Hi all, I also have the progesterone intolerance.
I am on Utrogestan, taking it for half the month. Had started using it vaginally after reading that may help
The first few months I was ok with it, I felt really tired and like I had a hangover but can cope with that.
However, subsequently I started getting terrible migraines and light sensitivity...and extremely low mood, I felt like I may try to take my own life, but for no particular reason. I just felt everything was pointless.
Every time this happened I immediately stopped the progesterone and i felt fine within 48 hours. Then my period would come early, as I'd effectively shortened my cycle.
Last month I cut the dose to 1 pill instead of 2 and that really helped.
I'm worried that I could get cancer if I do t take enough of it? Also if I keep needing to stop it early as the symptoms are just too terrible.
I can't really afford a private consultation and my GP is worse than useless, took months to get them to prescribe Estrogel and utrogestan as the argued that it didn't exist and that I had to have patches.
I found this info on the Louise Newson website. Seems to say it's ok to take only one utrogestan? But I guess that would be backed up by scans which I won't be able to access
