Hard uterus in the morning?

I’m 16w2d. Whenever I wake up in the mornings and roll onto my back, it feels like my uterus is pushed out and hard. I always thought it was because my bladder was full and pushing on it. This has been happening for about a week or two.

Is that normal? Or should I be concerned about it? Is it even my uterus?
