Dilated?

Jessica
Went to the doc today, and im 1 cm dilated! I wasn't expecting that at all! I know some people can be at 1 or 2 for several weeks but still its progress! Not due till 10-18 but the baby is measuring a little on the big side, about 1 week ahead...I'm 36+1  but the measurements say 37+1 and baby girl is 6.6 lbs already! Says EDD is 10-11 on the ultrasound I got today 😜
Anyone else dilated already?
