I'm sure everything will be ok... I have had 2 boys and with my oldest son he was the same way he didnt even make it to his due date and then my dr said oh wow I guess I had it wrong he was born heath and 8lb 7oz. So try not to stress to much...everything will be fine :)
You could have just ovulated earlier. My baby measured a week ahead and my due date changed. I simply ovulated really early in my cycle. I wouldn't stress.
Actually I care because now he's 2 weeks ahead , & because of my conditions I think he is going to be a big baby
I believe is ok...im 13 and mine said same...i was measuring 14 ajajaja so who cares ajajaja better more than less ajajaja
