Chart of estrogen / estradiol levels in early pregnancy?

[Anonymous]

I'm not finding good info about desired levels online. Anyone have a favored source?

Anyone? Feel free to just write about what you know about the need for Estrace in early pregnancy.

I'm taking it for a non-IUI/IVF pregnancy and it's something the RE never discussed in person with me. I'm taking it because the nurse called back with the RE's prescription about my first Beta draw. (I was already on progesterone supplements because of multiple chemical pregnancies.) I can't find much about it online that seems to correspond to my situation.

Are estradiol levels supposed to be at a set level per week or just at a certain level throughout the first trimester?
