Scarlet - Thanks! From what I can gather, for aCGH testing, my clinic freezes after 1 day, then thaws and grows to day 3 to be tested when it is booked in. I suppose we could have timed the EPU so that they didn't have to be frozen but we just booked both EPU and testing for as soon as we could. I have not been a fan of my fresh transfers anyway. Although it sucks to have to wait, I never really feel like my body is quite right after an EPU. Good luck on Friday!!!!
