1 day 5 morula left from pre-cancer treatment batch, losing all hope

Hi! I was curious to know it anybody was in a similar situation with an embryo cohort and what the outcome was. I’ll try to sum it up. In 2015, before undergoing cancer treatment that was so leave me infertile, me and my husband managed to do 1 round of IVF in which 5 day 3 embryos were frozen. We were quite young at the time (26 & 27) and the 5 frozen embryos kept our hope alive of having a biological child. After many years of unsuccessfully fighting the damage cancer treatment did do my body, we finally made the hard decision to undergo gestational surrogacy with our embryos. It is medically impossible for me to carry a pregnancy.

Upon defrosting, the embryos were left to grow until day 5. 2 of the 5 embryos were discarded, and of the 3 remaining, 2 were graded BB and 1 was graded as a morula and refrozen.

The 2 BB embryos were transferred, they implanted, the gestational sac formed but they failed to develop. I am devastated.

The 1 morula is all we have left and I know that the chances are slim for it to even survive the defrosting again. I cannot do IVF again, because my ovaries were literally fried by radiation and I am in early perimenopause, with a AMH of 0.18 and a large hydrosalpinx that needs surgery soon.

Communication with the clinic is quite bad so I’m not even sure I can get detailed infos about the morula, as it had no other description in the ET report other than the fact thay is… a morula.

The next ET is scheduled for early summer.

It was explained to me that the fact that the 2 embryos implanted but failed to develop means they were abnormal (they were not pgt tested). So if 4 out of the 5 embryos were basically abnormal, is there any chance the morula could be normal? I’m not looking for false hopes, I just need some answers that my clinic is not giving me.

Thank you!
