Thanks!

Lenny - it won't be a natural thaw cycle - my clinic uses lots of support (and although it's a frostie cycle, it's a bit more complicated in my case) and I'll be on a fair amount of progesterone starting a few days before transfer and building up through the first 8-10 weeks plus whatever drug they use to stop ovulation before transfer (to let the lining really build up) - can't believe I am not remembering the name of the drug! I'm going to look up my notes from my last cycle and call Monash.
