bioidentical hormone therapy

I have recently found a great ob/gyn doctor. I started 100 mg progesterone cream a month ago, no problem, actually felt a bit calmer. 5 days ago i started .5mg estriol, 0.0125mg estradiol, 100 mg progesterone all together in a cream 1ml a day. 5th day into it, started feeling very shaky, reved up, and anxious. I am 2 years post menopausal, 128lbs 5'6" in good shape. I called the on call doctor and she said to cut the dose in half until I spoke with my doctor. I am just looking for opinions on all this. Had hormone panel done, everything in the basement. On call doctor said my body is trying to get use to it, but is cutting it in half the right thing, will i still get enough progesterone.  thank you , so confused.
