Interesting. I am also prescribed progesterone (capsules), and I didn't really get any push-back. When I started HRT, my doctor had said that we could consider it once she had gotten my estrogen levels where I wanted them, which she had said would be after about a year.
Well a year on HRT later, and blood-work showed my estrogen levels were within the lower range for women. So I asked her to increase my dose one more time and prescribe progesterone, and she did without hesitation, after explaining it a bit.
I'm really lucky to have such a great doctor. I'm in a deep red state, and it takes an hour to get to my doctor appointments in the nearest blue city. I guess I'm also lucky that it's only an hour each way.
I have two somewhat personal questions for you, if that's okay:
Do you intend to take progesterone for life, or are you expecting to stop taking it at some point?
Do you take it everyday?
I currently take it each night, but only for the first half of the month each month.
