Not at all. We did tons of testing. Finally when it came down to doing pgs when we wanted #2 and 2 spontaneous miscarriages and 2 additional chemical pregnancies we didn't have enough embryos and I ended up preggo and now 23 weeks
With my first we had never done pgs as my re didn't think it was necessary and it took 3 full ivf circles and 3 FETs. I wish we would have pushed for pgs sooner because I feel like it would have made a difference. We finally switched res after poor care and being treated badly and it worked first try at new clinic but after the mcs above. (So it was ivf #5 in total and 11th transfer). Pgs was the only thing left to try.
