Uterus feeling tight for extended periods of time?

Hanna

Either it just feels this way all the time and I only notice it when I lay down, but I feel like my uterus has been more “firm” or something the last couple days. Is that how it is supposed to feel and I just didn’t notice it before? For some reason I thought it was more squishy but maybe it’s because my bump is finally starting to stick out more. Does everyone else have a firm feeling lower belly? Not having any cramps or pain or anything.
