Hi Tracey,

I'm not sure either and will be interested to see the replies. I just had my E2 levels checked yesterday for my 1st IVF cycle and it was 400 after 6 days of stims. (150 puregon) The nurse called and said it was borderline low and they would check with the doctor today and see if he wants to up my dose or keep me on the 150. We planned this cycle so we could go through all of this while DH was on holidays from work so i will be devastated if i'm not responding well and have to cancel.
