DG, I'm not very knowledgeable on these things myself, but apparently, it is usual to put younger women on BCP instead of HRT - I haven't tried any HRT because my GP said any of the HRT available would be too low dose for someone my age. So I just use the BCP plus Ovestin cream to deal with vaginal issues.
I assume I am still peri but have no way of knowing unless I come off the pill. I started getting my first symptoms at 35 though didn't realise what it was till last year (I am now 40).
My current GP ran all sorts of tests including thyroid, iron etc to rule out anything else - as she said, especially with younger women, she likes to rule out anything else before assuming it is menopause. She said that blood tests wouldn't be accurate for me regarding that, but based on my symptoms and having ruled out other options, she was ok to diagnose early perimeno.
Briony, thanks for the info on Qlaira. If it's lower dose, it sounds like it might not work for me. I think I will keep going with Ovranette back to back for now and see how I get on. I manage ok while I'm taking it - ok, so I don't feel the way I used to pre-peri, but I think it's as good as it gets now! And if I only have to have a break every 3 months, it will make it more manageable. I'm a bit nervous of swapping pills in case a lower dose makes me feel worse all the time - as I said, my GP is booked up weeks in advance, so if a change of pill goes badly wrong, I've a long time to wait before I can see her again. (Oh, yes, I could see the other GP instead...the one who ALWAYS has same day appointments available...which tells you all you need to know about that GPs abilities!)
