Hollybolly is correct - After having 26 and 35 eggs collected for my first two cycles and getting quite ill (but still eventually ending up with 4 and 7 blastocysts to freeze) I was initially ecstatic to find out I'd got 20 eggs for the third cycle and would be allowed to transfer.

It all came crashing down the next day when I found out that only 12 eggs were mature and only 3 embryos had fertilised...

I'd written off the cycle (one day three put back and the other two frozen) and was planning out how to save up for the next one because I didn't even believe the two frozen embryos would work... and now I have a two year old boy and two frozen embryos.
