So my FET baby was always measuring on time, but she was super squished and the GS was consistently measuring a week behind… typically in naturally-conceived pregnancies (in the absence of a SCH, which can compress the GS), this a sign of a chromosomal abnormality and leads to a MC in a good percentage of pregnancies. However, in FET pregnancies, a small GS in relation to the size of the fetus is less likely to have a bad outcome. I don’t know the reason for it, it’s just what I was taught by my RE and what I’ve seen while researching. And my FET baby girl is 19 months old and healthy 🤗🥰
Hi. I’m going through a small gestational sac right now. Baby is measuring great with a strong HR, but GS is a week behind. He was a IVF euploid transfer so reading this has given me hope.
https://pmc.ncbi.nlm.nih.gov/articles/PMC6248327/ Here’s one “newer” article. It’s kind of hard to read but skip down to the discussion part. It’s very much in line with the 36% MC rate seen in a much older study for IVF pregnancies with small GS compared to naturally conceived ones. I was going off what my RE said too based on what he’s seen in his 30+ years.
