I'm 39 weeks and my fundal height is at 44.

You can measure some ahead or some behind. If your doctor didn't display any concern, then don't worry about it!😊

I'm measured a ahead with both this pregnancy I have extra fluid and baby is bigger but healthy and my son everything was fine when you get further along every baby grows at different rates if you continue to measure ahead they will just do growth ultrasound don't stress about it
