40 weeks and no signs of baby coming

For the past couple of days I have been experiencing what I think are contractions. They have not been too consistent, they will be constant for about an hr and stop for a bit and have some in between and then again. A lot of stomach tightness and pressure, I feel like baby boy is about to pop out but my at my check up(3days ago) I was only 1cm dialated. Today I am 40 weeks and I have not had any discomfort whatsoever, no contraction, no tightness, pelvic pressure, nothing! I slept like a baby last night, when I usually wake up 5 to 6 times a night to use the bathroom. Baby movements seem to be normal but it's just weird. I guess I was just kind of expecting things to feel different since today I'm 40 weeks. anyone else experience this? I guess baby isn't ready yet. I just wanted to add that i am only experiencing some achiness on my lower stomach and inner thighs, like when you work out and feel sore.
