Mine hurt. It felt like my kidneys are hurting at first, (No I was not dehydrated, I drink a gallon plus of water a day.) but as I got further along my stomach tightens more with it and it's more intense. Sometimes I have to stand up and sway my hips to relieve the pain. Everyone is different you may just not feel them.
I rarely feel them. Only if I'm really dehydrated. Every pregnant woman gets them but you don't always feel them. And if you stay hydrated they won't be that strong.
It doesn't really feel like a cramp. They usually don't hurt, though I've heard some people say theirs do. For me my stomach just gets really tight and hard.
