I've been having problems with my E2 levels from the beginning, even before I started IVF cycle it was low, on day 4 of GonalF, E2 was 77, which they said it was very low (Dr said it was suppossed to be around 100 at this time), the next day it went up to 141, I don't know if this is still low? I'm going tomorrow again for blood work and u/s, tomorrow is day 8 of GonalF, so I think retrieval will be anytime soon and I want to make sure my E2 is right! Any advice?
