EDD for FTS scan different from first dating scan

It's normal for EDD to change /- 1-2 days diff in early pregnancy due to cycle, mine changed twice but difference only by 2 days. After that my gynae said to just stick to the latest EDD, currently I'll be 18 weeks tmr and it has been the same ever since. 😊

mine changed from 5 Feb during my first checkup, to 3 Feb during my next, to 10 Feb during my detailed scan. it's normal!

I guess so depends on your gynae. My gynae changed mine 3 times. Followed the most exact during nt scan.

Follow the first EDD. Subsequently your EDD will change based on baby’s size.

asked my gynae the same question before.. he says stick with the week7-8 edd
