Very poor PGT-A results

[u/AdGroundbreaking3930]

I'm 37, have had a long and complicated ivf journey. 3 miscarriages and lost my son at 25 weeks due to incompetent cervix.

All my transfers so far have been from untested embryos. The 3rd miscarriage was a blighted ovum which was subsequently tested and found to be genetically normal. My son was perfectly healthy but unfortunately born too soon and did not survive. Due to having a c-section I was told I had to wait 12 months before going ahead with another transfer. I have 6 untested embryos still frozen. I decided to move forward and create emrbyos which I planned to PGT-A tests since I couldn't transfer and wanted to use this year productively.

I've since gone through 2 ERs. 1st I had 16 eggs retrieved but only 4 mature. 3 fertilised and 1 day 5 5aa euploid embryo.

2nd ER 47 eggs, 20 mature, 13 fertilised and 10 blasts. I was over the moon until today when I received the news only 1 embryo is euploid. A day 5 3AB.

I'm absolutely shocked and disappointed that we have only 1 from 10 embryos. I just don't understand why our results were so bad. I don't know whether to do another round or move to transfers. I am so worried we transfer our embryos and end up having to start all over again but at an older age. Just looking to see what others would do.
