Great news about Lou!
I had another scan this morning, and follicles of note (there aren't that many, but oh well) are now:
19, 17, 17, 16, 14, 13, 13, 11
So the top 4 have grown 3mm in the last 2 days, and the smaller 4 have grown just 2mm.
Am waiting on results of blood tests to decide when I trigger - egg collection will either be on Wed/Thu.
Sadly the leading follicle will probably be too big by then, but hopefully some of the smaller ones will start to catch up!
