^^ yep. I'd go by the first scan you had.
The later the ultrasound, the more inaccurate they get to be.
Dr ddnt say why I'm due Jan...he jst told me da due dat after a scan.I was sooo shocked coz my gyna told me I'm due 20 dec n date never changed in several appointments I had
If your due date changed it would be determined at your 2nd ultrasound that you receive at week 20 depending on how big your baby is.
Did the doctor say why he thought you were due in Jan?
I had an early ultrasound wen I was 10 weeks.....2day I'm 35 weeks and Dr said I'm 32 weeks
If you had an early ultrasound (arouns 6,7,8 weeks or so), that's what you should be going by.
