Untested embryos, transfer 2?

My first round of IVF resulted in my 1 1/2 year old after transferring one embryo. We then had to start all over as that was our only one after a mini cycle. For second round we did full IVF where we received 11 mature eggs and all fertilized and then 10 embryos frozen between day 5 and 6. I was 32 during that retrieval. We did a frozen transfer and transferred a AA embryo and all was fine but miscarried at 7 weeks. We did not test the embryos so assuming it was a chromosome issue? It’s against our beliefs to test so we will try all embryos. Our next transfer is in a couple of weeks and I’m wondering how many more embryos are abnormal? We have 9 left and wondering if should consider transferring 2 or too risky? Remaining embryos are all AA/ A/B B/A B/B and one poor BC. But as we see grading doesn’t mean too much. We would like at least 1 more child. Would you keep transferring 1 or try 2? Thank you for your time.
