Estrogen Levels

Hey Ladies,
I'm wondering about estrogen levels. I'm on day 7 of stimms. I have about 7 mature follicles and 5 are 18+
My doctor drew mans to see if my estrogen was still low enough to do another day of stimms to see if the smaller ones could catch up. My estrogen came back more than low enough at 700. I can't find anybody who had a level this low. Any thoughts/ideas?
