The NHS prescribes norethisterone which is a synthetic progestin. The progesterone I take is derived from yams and engineered to match the body's own progesterone. I believe the NHS does prescribe something similar, but because I don't get my HRT from the NHS, I can't comment for certain.
And no, it's not the progesterone that bloats me, it was the excess oestrogen in my body. Now I'm on the smallest dose, I don't bloat. Also, is it inflammation or actual bloating? During menopause, a lot of women suddenly find themselves with food intolerances and unable to digest food properly which results in bloating. It might be worth adding in some probiotics too.
If your sleep is fucked, then that is definitely a sign your current HRT cocktail isn't right. Or, it might just be that you will need some melatonin, one that works in two parts - first to get you to sleep, then more kicks in to keep you asleep. Progesterone induces sleep too, so you should be taking this in the PM. I take melatonin at around 9:30pm, progesterone (in the form of a lozenge) and a dab of oestrogen (on my forearm) an hour later. Twice a week, I also use Vagifem (a pessary) before going to bed. In the morning, just a dab of testosterone, again on the inside of my forearm. At each stage, it took a few goes to get the levels of everything correct. For me, it was always sleep and my body odour that were most indicative of the cocktail firstly not being correct, and then, correct. But, as I have said previously, perimenopause, menopause and HRT is so highly individual, that we all have different needs.
Lastly, are your adrenals supported? Adrenotone by Designs for Health is really good as an additional supplement.
Good luck! Keep pushing until you feel great!
