Apparently the same protocol as last time gave significantly different end results. The multiple eggs I had a few days ago have turned into one 20mm egg with lots of small ones but still with a good lining 12.4. So, so disappointed. Luckily, I can get one egg on my own so I am a bit miffed to be spending the time/money/stress to get one egg a cycle. I seriously considered not doing IUIs this cycle but I guess we're going to go ahead.
