Hope following fertilisation failure?

Hi everyone. I had an egg collection on Monday. We got 4 eggs but unfortunately none of these fertilised following ICSI. I’m completely devastated. After 4 rounds I feel like the journey might be coming to an end, and I’m not ready to face the idea that we might not ever have a baby. I’m looking for a bit of hope. Anyone else on here had a round with failed fertilisation and gone on to get viable embryos in subsequent rounds? For info, I’m 37 and have been doing IVF since 2022. -Aug 2022: fresh cycle, 7 eggs, 3 fertilised, 1 blast, BFP. Ended in chemical pregnancy -Jan 2023: fresh cycle, 7 eggs, 2 fertilised 1 morula: BFN. -April 2023: fresh cycle, 7 eggs, 1 fertilised, 1 4AB blast. Freeze all. -May 2024: FET, BFP. Ended in MMC. -Feb 2025: fresh cycle, 4 eggs, none fertilised.
