Just an update - I needed to go to the chemist to get some scripts filled so I had a chat to the pharmacist. She said that the dose that is "recommended" is a bit of a "to be on the safe side" kind of thing and that basically the dose of Provera is quite variable and is going to be very dependant on the woman herself and what kind of job it does. She said if I'm on a medium estrogen dose, and taking 5mg a day for half the month is giving the desired result (ie a good bleed with no negatives like breakthrough bleeding, bloating, spotting etc) then that would be an okay dose for me.
Seeing as my doctor is aware that I'm a bit sensitive when it comes to progestogens, she has obviously gone with this dose and will rely on me to report anything odd. The only time I've had any kind of spotting or breakthrough bleeding is during the 2 months I was trialing the conti patches, which ended up being a fail anyway. When I use the Provera @ 5mg for 10-12 days I've never had any of those issues, although to be on the safe side I will now use it for the full 14 days. I may also try to spread it out to every 6 weeks and just see how things go.
I have asked my doctor in the past about the scans, but she's never been too concerned about them. She said as long as the bleeds look normal (good colour, no clots etc), and there were no other signs like the breakthough bleeds etc, they usually aren't necessary. When I mentioned the scans to the pharmacist today she also said the same thing.
The reason I was being so concerned about the dose that Sunnydays was being prescribed is because she has already said she had progestin issues after using the conti patches. This is exactly the issues I've had too, and I know I certainly wouldn't want to be taking 15mg per day of the stuff. So I just wanted her to be cautious about considering such a long cycle and perhaps needing such a high dose each day.
So anyway I just thought I would post all this to help anyone else who may be a bit confused. Don't take too much notice of what dose others may have to use. Always look at the results you are getting as a guide to what is right for you. I think sometimes we just need to relax a little and go with our gut feelings about things. Sometimes reading a lot of stuff on the internet, and forums like BB, can make us a bit OCD about things. We have to remember that we are all different, and if something is working, and there doesn't appear to be any problems, just go with the flow (no pun intended..lol...). Menopause can be hard enough without making things harder for ourselves by reading too much about things that may never happen or may not apply to us.
Mind you, if the day ever comes when I can either stop HRT altogether, or even reduce the dose, I think I will be a happy puppy, because despite being a big advocate for HRT, and all the benefits it can bring, there can be a big downside too if you have progestogen issues.
