2 retrievals with different pgs testing outcomes?

Heather.

I just did my 3rd egg retrieval. I had 5 retrieved, 4 fertilized, 2 embryos, and both came back abnormal. I’m 35. When I did my first two retrievals I was 32. Those two resulted in 5 pgs normal embryos from 24 retrieved, 6 blastocyst, and 5 normal.

I’m wondering if anyone did two back to back cycles and had different outcomes with pgs tested. I want to do another cycle and my doctor says each cycle can be different but would love some others experience.

I have one embryo left on ice but I want to try and bank some more given my age, low AMH levels, and reoccurring miscarriage history.
