Cycle 4 Timing

I went back to the doctor yesterday for another ultrasound. Did I mention how much 4 hours on the road sucks? Sorry, I am not a fan of driving that much, especially alone - usually B does all the long distance driving. Anyway, it was CD 13 and the dominant follicle had grown to 18. Actually it was 14x18 which was a little weird but my doctor said the 18 is what counts. So I will be taking the Ovidrel shot tomorrow night, trying to make a baby Friday and Saturday, starting progesterone on Monday, and taking a pregnancy test the 28th.
