Hi first time poster here, any help appreciated. How often are early pregnancy scans inaccurate? TV scan was completed and GA is 7weeks 1 day from lmp, according to the person being scanned the scan was done at a private clinic, I’ve been advised that it was 5weeks 5days pregnant but could also be only 4 weeks as too small to say for sure, does that sound right? I take it the 5weeks 5days would mean from conception? Any help appreciated thank you all
