I had 13 blasts that time and they tested 9, I had 13 tested the cycle before and had 3 normal ones and the cycle before similar amount of blasts but only 1 normal but that was day 3 testing annoyingly and I think if had been day 5 then I would have had more. I always had a lot of eggs, I think if had just 1 or 2 embies then I would either bank them and do a couple of cycles then test all together or just not do pgs and have them transferred,its a lot of money to pay out for 1 or 2 embies. For me it was essential as I had a lot of embies and most top quality but would have been repeatedly transferring embies that would have progressed and along with paying for the immunes it just wasnt practical so I wanted to know that what was being transferred were viable and I could concentrate on finding the treatment to help me hold onto them
