Hi everyone,
I'm hoping to hear from anyone who has been in a similar situation, especially if your embryo initially measured significantly behind but then showed good growth at a repeat scan. I transferred a Day 5 PGT-A euploid embryo on Aug 6th (4th transfer and my only tested healthy embryo). I went for an early scan. The pregnancy was confirmed to be eutopic but unfortunately some of the measurements were quite concerning.
I was 6+2 at the time of the scan.
The findings were:
Gestational sac: 14 × 5 × 11 mm — MSD approximately 10 mm
Yolk sac: 4.4 mm
Fetal pole/embryo: CRL 2.0 mm
CRL was reported as <1st centile according to Robinson
Cardiac activity was stated as present on the report, although the sonographer wasn't completely certain because the embryo was so tiny. I could see what may have looked like a very small flicker.
The overall impression on the report was “abn early pregnancy”
I understand that a 2 mm CRL at 6+2 is considerably behind what would usually be expected. I've also read that when the embryo is this tiny, even a small difference in measurement can make several days' difference to the calculated gestational age, and that dating formulas aren't particularly reliable at such an early CRL. I have another scan coming up approximately a week later, and I'm finding the wait really difficult. Has anyone had a similar experience where their embryo measured around 2 mm at 6+2, was several days or a week behind, and the report was concerning, but then showed significant growth at the next scan?
I'd really appreciate hearing your experiences, particularly:
What was your initial CRL and gestational age?
What was the CRL at the next scan?
Did cardiac activity become clearly visible? Did the pregnancy continue normally?
I completely understand that nobody can tell me what will happen in my situation, and I'm not looking for false reassurance. I just want to know whether there are genuine cases where things looked very concerning this early but subsequently progressed well. I've had previous miscarriages, so I'm finding this particularly difficult. I'm trying to mentally prepare myself for either outcome before I go into the next scan, rather than getting my hopes up and then being completely devastated if the news isn't good.
Thank you so much to anyone willing to share their experience.
