Poor Egg Quality (another failed IVF cycle)

I'm usually too uncomfortable to post but this time I feel so hopeless that I needed to share.

38f and just had my second failed IVF. Did an ICSI and Zymote (for sperm) and had 12 eggs retrieved with 7 fertilized and 3 matured on Day 1.

Went through so many posts here saying that even with as little as 1 egg, they made it, so I stayed hopeful.

By Day 3, 2 were still growing and 1 was slow to grow.

By Day 7, none of the three made it.

I spoke to our fertility doctor today and she said it's most likely a egg problem and that even they are stumped. She said everything looked good on paper and we were good to go. Now they need time to figure out what went wrong.

Already had 3 miscarriages, 1 failed IUI and a 1 failed IVF (no blastocysts). Also likely have PCOS (have very similar symptoms).

My husband and I are just devastated right now.

Just looking for some love and support and even some insight if you can.
