Any positive stories of IVF success with pgs normal 7 day blast?

Hello all! I just finished my first (and only) IVF cycle and after pgs testing we ended up with one normal embryo. It is a 7 day blastocyst. A female. I know some places don’t do 7 day blasts yet and I have read that the success rate isn’t as high but there is not much overall information out there as it appears allowing the embryo to grow until 7 day is fairly new. My embryologist did share they are having good success with 7 day blasts that are pgs normal....but I was just curious if anyone I heard anything about 7 Day blasts or any success with them? Thanks in advance!!!
