Who did your consult and testing for the bioidenticals? I would contact the compounding pharmacy and ask about it. The compounding pharmacy that does bio identicals in my town includes consults and support as part of the fee when they test and prescribe, then you only pay for your hormones separately. But here a nurse within the pharmacy handles all of that. They really should give you more guidance.
I do understand your frustration though. A midwife in my gynecologist group was very vague with me, told me to buy progesterone cream and estrogen spray at a health food market, and wasn't clear on how much to apply. I did not follow her advice, because I didn't understand well, stuck it out for another year, then went to my gp and was given estrogen patches and progesterone pills, thank heavens. Of course, in the meantime I had researched on here and basically told my gp what I wanted, but I do feel better doing it under his guidance.
Edit: I just saw your other post. So of your 3 choices from 3 doctors, you've chosen estrogen and separate progesterone cream? Good choice, I think. You said you felt like your gp was giving a standard answer and not tailoring for your needs, let me see if I can reassure you. They have to start somewhere. It really is a guessing game, and looking at your specific hormone levels doesn't necessarily tell what dosage you're going to feel best on. Some women feel fine with a given blood estrogen level, while others need double or triple that level in there blood. Everyone is different. The idea is to take the lowest dose of estrogen that helps you, and the progesterone is used to protect your uterus from overgrowth of the endometrium. They need to start with a low standard dose and see how you react. If it fixes everything, great! If not, you'll be able to say, for example, that nothing has changed, or that you feel good during certain times and terrible others, or that you're having irregular bleeding, headaches, whatever may pop up. From there, things can be tailored to your needs. The separate estrogen and progesterone creams lend themselves to adusting very easily, as your can use more or less as needed. BUT, don't go changing it up daily or you may find yourself in a real mess. Start with a minimal amount (Mary G will have to help you here, I don't know the gels) and if after several weeks you're not well, you could try more. I believe the progesterone would need adjusting based on spotting or bleeding problems, but you really need to talk to your prescriber about that. I don't think there are many(any) on the forum that use compounded progesterone cream.
Sorry for the novel!
