Waiting and praying is dna to blame ?!

Hi girls

I went to the hospital yesterday for my follow up after egg collection where they were all frozen

Good news we have 6 out of the 8 collected frozen

1A 3B 2C

Not so good, they were frozen day 2 as last time day 3 they stopped developing properly.

The doctor said my eggs seem fine and Hubby's sperm seems fine but there could be an issue that needs further tests which will be in sperm which is apparently is easier.

I'm now praying that one sticks and survives in January \ Feb time as my next appointment to start the FET is the end if Jan.

Anyone know about extra tests, dna, etc that has had this happen to them?

Baby dust to all
