My uterus has been hard since I woke up (about 30 minutes). It feels like a contraction, but I don't know. I have pains in my belly button like what happens when he's growing and his body is pushing my belly out further. Its tight. I can feel the difference between my son and my uterus. Where he is is extremely hard and around him feels tense, somewhat squishy, but not too much. Its definitely not the usual feeling of it. Usually its squishy around him. What is this? is this just a long ass contraction?

38+6 btw. Forgot to include that.
