Our first embryo transfer (PGS tested day 5 embryo) was done mid-November; no heartbeat at 7 week ultrasound and unfortunately the 9 week scan showed no viable pregnancy; plan is for D&C later this week... wondering how long we have to wait until going for a second embryo transfer? Has anyone else had experience of an unsuccessful transfer with a PGS tested embryo? Devastated to be going through this...
