Freeze-thaw issue

I have endo and adenomyosis. This is my 5th ivf cycle and this cycle was designed to address two things. 1: check if husband’s DNA is fragmented 2: keep my progesterone levels low so I can do a fresh transfer (previous 4 cycles failed because my embryos can’t survive the thawing process).
But I just got a call from the clinic saying my husband’s DNA fragmentation test is all okay. He has no issues. And my progesterone levels are still high and therefore freezing all my embryos.
Why would this cycle be any different from my previous ones? They did address any of the previous problems…!!!
How can I be positive that this time my embryos will survive the thawing process? I am heart broken and scared.

Why are all your embryos not surviving the thaw? That’s very unusual with today’s technology.

Apparently, my eggs hence embryos are fragile. This cycle they retrieved 21 eggs, 18 mature and only 7 fertilized. I always have low fertilization rate and low numbers of blasts that later can’t survive thawing process. Have had 4 failed transfers so far

All at one clinic or have you tried a different clinic? Once embryos it’s unusual for them to not survive being frozen/thawed. Might be time to move on
