Second IVF??

Ca

Hello Friends. I found out last week that our first embryo transfer came back as a negative pregnancy test. Lining was thick, embryo was excellent quality and PGS came back as normal. After a week of feeling hopeless I'm now starting to pick back up my spirit and look into the future. I have an appt with my RE to discuss what happened and what to do for our next transfer as we do have more embryos frozen. But wanted to see if any of you have advice for any other testing and/or questions I should ask before my next FET to better my chances? Thank you for your support.
