This is a hard one, as scubagirl said it is not the golden egg. You can transfer a known perfect embie and still miscarry because that it the mystery of fertility, your body can reject and perfect embie for many reasons.
All I can say is we did PGD on our last cycle due to my age and the fact we had a good looking fresh embie (not PGD tested) make it through all tests and sadly was found at 26 weeks to have Trisomy 13, our girl was stillborn at 28 weeks.
Based on that heartache and grief we opted for PGD ... we did a fresh cycle and also threw two frozen embies to be tested too... the outcome was out of 4 embies only 2 could be tested and then one came back abnormal and one was perfect. Little Miss Perfect is now 6 months old
I was told to cancel the cycle due to so few embies available for testing BUT we went against statistic and did have that elusive golden egg.
Talk to your FS.... maybe try and few cycles without and see how you go. Luckily NIPT tests help these days but even then do you want to go through to 10 weeks to then find out all is not well????
It is a difficult question.... everyone have different stories but I now that for us PGD made the difference.
