Success after PGS loss?

Cossab89

Hello, I am new here, but not completely new to IVF. My first cycle resulted in 3 5d blasts but only one was PGS normal. That cycle failed. My second cycle we had 5 5d blasts but 4 tested PGS normal. We were thrilled! We opted to do the ERA and found out I was pre receptive and needed an additional 24 hours of progesterone. I did an FET on Valentine’s Day and nine days later had my first positive beta! 116. It continued to double and the last beta I had was 6675 on the same night we saw the sac and yolk sac. Everything looked great. Three days later I began heavily bleeding and cramping and that was it. Now what? My RE claims it couldn’t be chromosomal because we did PGS. I don’t want to try again if something else could be wrong. Was anyone else successful after a PGS fail?
