@ScubaGal @KitiK is right. FS said there was only 5 maybe 6 at my scan. EPU came around and they found 9 (they can't see all of them, they hide the tricky little buggers)
I too used the visualizing technique and would you believe I was right with my numbers.
I visualized that we would get at least 6 to 5 day blastocysts. And we got 5 we have previously never got more than 2 to 2 days
I believe in putting it out there into the universe
