That was not mentioned as an issue for me either nor was I tested for it (but my clinic does very few BT during the cycle - only day2 fsh.

I think it is worth asking your FS how much of a difference there is between flare without pill and antagonist - my experience was that they are virtually identical except for the syranol which has nothing to do with egg quality or quantity but does do away with the concern of ovulating prior to pick up. I mention this because if you are looking to see how you react to something different adding the pill in there may be worth considering otherwise I am not sure if there is much of a difference.
