2 transferred, 0 left to freeze. How?!

[Sandra00]

I froze eggs when I was 37… took 11 out the freezer and combined with a fresh cycle where I got 9 which was a pleasant surprise. I had 15 fertilised - 7 from younger eggs and 8 from fresh cycle. I was over the moon.
fast forward 5 days there’s only 1 blastocyst and 3 early blasts they didn’t know would be suitable to freeze.. they transferred 2 (my good blastocyst and another) I went down this route as the doctor advised me to as I may not have any to freeze so I thought may as well pop another in, as I’m okay with twins.
Today I get a call that I have 3 day 6 blastocysts but they won’t freeze them due to their cell number is this normal?! I really want them to but they said they likely won’t survive freezing and unfreezing. I also have 2 more early blasts that they will update me on tomorrow… but I’m not sure how hopeful I am now! This journey is so tough.
I know I have 2 inside me and should be hopeful like I have been in previous rounds but I feel worn down by my results this cycle and wish I’d kept those 11 eggs in the freezer now as maybe they would have done better another cycle.
I also have a slight fear that they put the embryos in too early and wanted to know how many days progesterone before transfer you have had??
I was told to start progesterone Friday eve.. Then the transfer was around 11:30 am Wednesday. That’s 6 hours under 5 full days, is that okay??
looking to hear your stories to give me hope and also wondering if anyone else has experienced getting blastocysts they can’t freeze and why this has happened.
thanks x

It seems so strange they won’t freeze them, they should give more information into why,
did they use icsi ?
reference progesterone I had 4 full days before transfer and assumed that was the norm

@Sandra00 which clinic are you at and did they tell you the grade? Some won't freeze below BB.

@sirensong guys and st thomas hospital in London
@camelinastorm Thats good to know that you had 4, maybe 4-5 is the norm then, did yours work?
This journey is SO LONG, just hoping I get there and that 1 of these 2 embryos stick

@Sandra00 Try not to second guess your decisions; you made good choices based on advice from experts. The drop off from fertilization to blastocyst is normally high. It's from day 3-5 that the issues arise so fertilization isn't an indicator of success. I remember being devastated after being told all 15 eggs had fertilized once only to get 1 blastocyst and that didn't work either. Then from 40 there's 15-25% chance of normal eggs so the odds are of you getting a couple of blastocysts overall. Regarding freezing, if they aren't well expanded etc then that is why. Again, brutal but they know what to look for. For us, it's personal and subjective but for them it's objective and fact based. You have thrown everything at this, it's so exhausting. I remember your other post and I've been rooting for you. And you still have a good chance with your transferred blastocysts. What was their rating? Thinking of you and sending a hand hold.

@Sandra00 up to now yes I have had positive tests but only 5.5 weeks so won’t know how well it’s gone until the scan

Thanks @Sara237 really appreciate it. Very kind. Did you find out why you only got one blastocyst or are these just normal attrition rates? Did you get pregnant in the end?

@camelinastorm Congrats that’s super exciting! Was it your first transfer?

@Sandra00 no I think it was out 7th transfer, I lost count 2 I had no antibiotics for the first 2 as that clinic didn’t recommend it.

4 were then early miscarriages and 2 failed implantation and this one it’s still early so we have to hope we get past 7 weeks

@Sandra00 From my time on these threads over the years I think it's just normal attrition rates. At 38 I had 2 IVF cycles, lots of eggs, always fertilised but only 3 blasts from two cycles, about 25 eggs as I recall, first blastocyst didn't stick, second gave me my perfect son, now 8, one frozen from this cycle, didn't stick. And I'm the picture of health, don't smoke, drink, fit but it's just the age of the eggs...it takes so many more.

@camelinastorm What a journey but glad you got there in the end, fingers crossed for you. What do you mean re antibiotics? Is it best to take them? Why?

@Sara237 Thats lovely you got your son. Good to know re attrition rates. Are you going for another round? Spoke to my clinic today and one early blastocyst from yesterday is borderline okay to be frozen it’s a 4CC so not sure how much hope I have for it but also glad to have one in the freezer from my younger eggs! Just praying one of these embryos inside me sticks! I’ll keep you posted!

@Sandra00 Everything crossed for you. My son was a lower rating than that and he's perfect! Our frozen one that didn't work was higher rated so don't get too worried about ratings. I'm now 21 wks with a donor egg pregnancy. Which I should have done much sooner! Good luck!

@Sara237 That's so good to know, thank you!

also @Sara237 huge congrats on your pregnancy!
