My E2 level yesterday, day 5 of stims, was 364. Nurse Through on the voice mail message seemed really pleased with it. She even made the comment "your E2 levels are so nice at 364 that Dr. Cupcake has decided not to make any changes to your medication routine."
But I can't stay off the Internet and I had to get a 2nd opinion from Dr. Google. I found this chart from Advanced Fertility Center of Chicago (here is the link http://www.advancedfertility.com/ivfstim.htm). And though it has no specific numbers from 0-1000, I think I fall in the "normal" range.
