Failed cycle

I had my 4th retrieval last week and found out today (day 7) that we didn’t get any blasts.

my baseline afc was 8

we retrieved 12 (the most from any cycle)

9 were mature

4 fertilized

0 blasts

i have had some success with embryo banking in precious cycles, so I am not as distraught as I could be. I have a few day 7 euploids banked. we did this hoping to get day 5 or 6s. I know day 7s are not as likely to implant, but I am too exhausted from egg retrievals. I’ve done 4 in succession - sept, oct, dec, feb and I am just exhausted from the whole thing. i dont think there is anything I could have done differently. I know that I did not do any to do this cycle, but felt like I should at least try. maybe that has something to do with it. who knows. I am just so sick of IVF.
