1 week behind on early scan

Yes it’s normal! I thought I was 6 weeks too upon my first scan but when they did the abdominal ultrasound I was only 5w 4d. Could see the flickering heart too! Was told to come back again in 4 weeks and was told I was actually 11 weeks instead of 10 weeks! They even changed the EDD from 25th Oct to 19 Oct. Don’t worry. It’s still too small to detect the the age of fetus at the moment. Just continue with your folic acid until your next appt.

Yup, both my scan dates were at least 1 week different from the dates calculated by last menstrual period. Heh. Just follow the date on the scan:)
