Gestational age or gestational age by dates

[macdat]

On my notes, I have two possible due dates written down. I have two ages written down too. One says gestational age, the other is for a week later and says gestational age by dates.

Now I'm worried that I'm the further ahead date, but maybe my baby is developing a week slower than it should or something.

Has anybody else had two different gestational ages?

Ones your dates as in gestational age from due date and other would be the gestational age as in the age it's measuring at. My original gestation age by dates was 3 weeks ahead so was put back and then my baby was a week ahead by measurements and now's ages on target. It's nothing to worry about if they are not worried and normally a week or so out isn't a significant different. Also measuring the gestational age by measurements on the ultrasound are always accurate xx

Are not always accurate*

My GA by dates is four and a half weeks out. Dates from the scan tend to be more accurate.
