Day 5 vs Day 7

Hey everyone, iam 38yrs old. I did ICSI no male factor issues. I Had 11 eggs, 9 matured, 7 fertilized and so far out of the 7 fertilized 2 have been biopsied and have been sent for pgtA testing. My embryologist wants to give it 1 more day to see if the other 5 will grow as today is Day 5. But should I tell her to give it 2 more days to get to Day 7? I really don't want to do another retrieval and I am nervous about what the final number of euploid embryos I will get after PgtA testing. What do you think?
