Make sure you do your blood tests and get to see your results. And if they're not good but they refuse to increase your dosage, insist. A lot. Or you might end up having a year and a half of estradiol on such a low dose that almost nothing happens like I did.
Also if you're ever a lot more worried about your liver than your doctor, I think putting your Estrace under your tongue is a valid option. Not that you SHOULD be more worried than your doctor without a reason.
Anyhow, good news. Congratulations.
