    My concern (I'm sure others share this with me) is that your RE does not plan to monitor your ovaries' response to the Clomid. It's my understanding that we cysters are more inclined to hyperstimulate. I did last Clomid cycle and had to take a month off. Who knows if it's happened before? I went to 4 Drs. before I found one who did monitor me while on Clomid.
