Come on little on

I’m 38 weeks and sign that baby is coming any time soon. Only 1cm dilated and 60% effaced maybe it’s because it’s my first. I do walking at least 20/30 min 2-3 times a week baby measuring 7 lbs. so ready for this little cookie to get here. I was thinking oh this my first she will be here at 38 weeks but I think this little cookie is going stay in till due date. Anyone else have they first early or right on time?
