I have two dominant follicles--one on my right (19mm) and one on my left (20mm). The problem is that the one on my right has very uneven edges and is abnormally shaped, which could mean I'm either about to ovulate or I've already ovulated. They took some blood work for a progesterone test and will call me in a few hours with the results.
If the blood work shows I haven't ovulated or I'm not ready to quite yet, then I'll trigger on Saturday night and the IUI will be Monday.
I'm happy the Clomid did it's job, but on the other side, it thinned my lining. So in addition to everything else, I have estrogen suppositories to take tonight and tomorrow that will hopefully thicken my lining.
If I had to guess, I would say they are going to cancel the IUI. But I'll know for sure in a few hours.
