I had 2 ovidrel triggers Saturday before last. I am pretty thin, 61kg for 1.75 meters which makes me think that in my case it was not weight related.
I had 18follicles on my day 8 scan, 15 on my day 10 scan, they retrieved 13 follicles on Monday, 9 fertilized, 8 made it to day 3 and 6 became blasto.
My best numbers so far out of the 7 cycles I've had.
A couple of things were new this time around: very high doses of menopur (450 daily ), double trigger and I'm a lot fitter than usual.
I am not sure exactly why I had a double trigger but I guessed it was one of FS 's great moves.

I wish you the best with your cycle.
