Thanks Mary G, well I am post meno, I am 56, so many different experiences for everyone!! Yes I have tinkered quite a lot with this utrogestan!! Was scared initially to use 200mg cos of the side effects I read about so I used 100mg for 7 days, then always using the 100mg utro used either for 10. Days, etc my problem was always extreme tiredness that I couldn't cope with whilst working, I've had various periods of bleeding, had a scan 6 months ago and the lining was thin, since then using utro at 10 days for 2 cycles got breakthrough bleeding and not much, lastly no bleeding for last 2 cycles at 10 days then the next month 12 days, so..... Realised this is not good I have to have a bleed so started 200 mg utro for 12 days, I plan to do this for a few months until I have a lining scan in mid August, if the lining is ok then I may lengthen my cycle to every 2 months, and have 6 monthly or yearly scans!! Now on 5th day of utro and yes it has made me very tired and foggy, but I just keep busy and ignore it then it seems to be a lot better! Also it has made my bladder funny and I do have bit of a bladder prolapse but I have upped the kegal excercies and it has really helped, so that issue has got a lot better! Sorry if I have gone on a bit, I think this site just lets us read about everyone else's experiences, get ideas, info and get it off our chests!
