Hi-I asked our RE’s lab embroylogist today if our 4 remaining embryos made it to 5 day blastocysts today. She replied not but they will check tomorrow. This has me really concerened we wont have any to freeze. She said they either freeze on day 5 or 6 but if none are showing blastocysts today what are the chances they will make it tomorrow?? I am so scared and worried.
