small CRL first scan

[Mrs_k2022]

Had my first scan at 5w6d yesterday (more so to exclude ectopic as I’ve had several previous) post successful 5 day FET. the paperwork they have given me said CRL is only 2.9mm and looking at journals and reference tables in books/clinical guidelines and research, this is considered much smaller than it should be.

I know it’s very early but according to my reading and research , CRL is considered pretty accurate at the 6 weeks mark onwards. And my scan was only a matter of hours before this! They are going to rescan in a weeks time and hopefully see some growth then. They also said there was a tiny heartbeat and yolk sac etc but the thing that worried me was the CRL as that is what I’ve found to be off. They didn’t say anything in the clinic but I guess there isn’t much to say until next weeks scan.

I guess I’m just spiralling and wondering if anyone else has had a similar experience with similar numbers and willing to share outcome, good or bad .
