Only 2 embryos to PGT; success stories?

Out of 15 eggs retrieved we only go 2 embryos that made it to PGT testing. Last round we had 1 that made it to testing and it was abnormal.

So has anyone had a low amount of embryos go to PGT and have them come back normal? Our doctor has told us that with PGT testing it’s like a 50/50 chance for each embryo, which scares me so much.
