Labor feels so far away!

Kirsty • 1st Baby Boy due 5/6/15 💙
I am currently 38 weeks and expecting my first baby boy. Due on 5/6 and it feels like it is never going to come.. I understand it's better for my little one if he goes the full 40 but I have had no real signs of labor on its way or even close. No sort of contractions, the occasional period like cramps in my lower ab but that is it. Doctors says my boy is as healthy as can be and he is very low but I am feeling like he will go over. Anyone else feel like this?
