How big is week 5 or 6 Fetus size consider normal?

my first scan was at 5w6d, crl measuring 0.29cm which is normal. The CRL is the longest length of the embryo or fetus measurable excluding the limbs and yolk sac. The gestational sac is the large cavity of fluid surrounding the embryo. maybe u have a longer ovulation period so the growth could be one week late? is this your first ultrasound scan?

I’m not sure whether it’s the same thing, but on my Week7 my CRL was 10.0mm & Week 9 it was 25.4mm. Currently in my Week 37.

Gyane said 3mm for my 6week old. She says normal though
