After dating scan Do you still go by your last period or by what the Ultrasound states? when it comes to how many weeks you are🤔

Question

Answer

With my doctor it depends on how the ultrasound and your last period match up. They won't change it unless your ultrasound was more then a week off. 
So I was measuring a day behind at my first ultrasound at 10 weeks but they kept my due date the same because it wasn't more then a week off.

Answer

I went by the scan just because my periods are so irregular and I was really bad at tracking them. 😅

Answer

by my last period I was due January 1st at the dating scan he was 4 days ahead but it was still close so they left it at the anatomy scan (usually 18-20weeks) he was a week and 4 days ahead so I think they finally changed his due date to December 22nd and they may do another ultrasound at 35 weeks if I make it that far.

Answer

My doctor said unless the dates are more than a week apart we keep the date of the last period.

Answer

By my last period I was due oct 19 but when I had my ultrasound I measured 4 days behind so they changed my due date to oct 23

Answer

By my last period I was 12 weeks but my dating scan showed I was 13weeks 3days so my due date changed x

Answer

Both of my date were November 24th 😊

Answer

I go by my period. It's one day difference, but it means a LOT to me lol.
I tracked my period, know the exact day it began, them tracked my ovulation, and know when peak day was. So I go off my own! Plus, it sneaks in 1 extra day to go over my due date if I don't try to correct them 😏
I'm only allowed to go 41 weeks since I had a previous csection. Add on a day, 41 weeks and 1 day. Could be the difference I need lol 😂

Answer

so you ladies are going with your scan date. Would it change again at the 12 week ultrasound?
