@Green lady will this be your first scan? Day 10 seems late. Oh don't worry this cycle is just as much trial and error as anyone's. I think that's what Ivf is all about especially if you don't fit in their 'standard' protocols.
I suggested some of these things after reading them online- if they will work remains to be seen. I really wonder about the double trigger thing but if you are also at risk of ohss there is no way they will do it I don't think. The second guessing is awful isn't it. That how I'm feeling. There's just no right and wrong in this I don't think, as everyone responds differently. Sigh.
Praying this works for you this cycle and you get all healthy PGD embies.
