Progesterone makes your body think it's pregnant
I had started Peri-menopause in my 30's. I went to my dr friend who put me on the pill AND premarin, at the same time. I mentioned to my dr friends wife I was using progesterone cream, and she said...Oh, don't do that, progesterone makes your body think it's pregnant. So I stopped. Now, 15 years later, I'm off all estrogen and self medicate with just progesterone. I feel better til I start to spot, then I stop progesterone for a few days.
