If you have a compounding pharmacy in the area, you can ask them the names of some doctors who prescribe it. There are quite a few OB/GYNs starting to prescribe them. You may want to look for a doctor who practices integrative medicine also.

I use a bio-identical estradiol patch called Villel Dot and then an OTC progesterone cream. It took about a year to get to the right dosing. I started low and worked up. I found if I didn't, it was overwhelming to my body. The progesterone was the trickiest. There's a bio-identical progesterone pill called promethium that I tried first and quickly stopped after about 4 days. Found I was waking up with very achey feet. That's when I switched to a transdermal cream at very low dose and worked up slowly.

I am post-menopausal and my goal was just to rid myself troubling symptoms. Some try to restore/mimic a cycle of a menstruating women but I wanted none of that.

I don't have PN but I have read that progesterone can be helpful in some cases.

Just know that it's a very individual thing and it can time to find the right balance.
