Day 5 embryo update ??

Megan

We had our day 5 update and were told all 6 embryos have 60-80 cells and we need 100 or more for pgt testing - so I will get an update tomorrow. But what happens if they don’t have 100 cells? Do we wait another day or does it mean those embryos then are no good not viable / abnormal? Any one have this before ?
