DH and i did one round of PGD for our genetic condition and got 3 embryos to day 5 but only one was good enough to be tested it was effected we decided not to do another PGD cycle it was all to much uncertainty and expensive and the odds were not good our odds of naturally concieveing a healthy baby were better so we took our chances and our healthy daughter is due to be born in 11 days.
It is stressful but if you can afford it and handle the emotional rollercoaster then go for it.
Good luck and all the best for this cycle.
