? For those with at least one live birth

I realize I'm overly aware of my body with this being my 4th pregnancy and fingers crossed 2nd live birth, but I have to ask if anyone else has this feeling. I figure it's my stomach stretching due to all the pregnancy craziness, but sometimes it feels like it used to when my daughter was moving around when she was bigger. Incredibly tightened and then released. Not painful at all. Definitely not like a cramp or contraction in any way. I hope I even explained it in a way that made sense at all. Any responses would be welcome at the moment, thanx gals!!
