LuckyStrike - I'm with MIVF too and I took crinone every night. I do wonder if different clinics vary the protocol but as I've only gone through 1 full cycle with 1 clinic (MIVF) I don't have any info on this. I'm in the middle of my 2nd cycle with them, and so far the protocol is the same except that my gonalF was increased. or to be more specific, in the middle of my first cycle after my scan, my FS increased the amount of gonalF and it is this increased amount that she started me on this time.
