Normal to feel crampy/constipated feeling

Currently 35w4d & since last night I’ve been having a crampy/constipated feeling in my lower part of my stomach. It’s not super painful but more painful than just uncomfortable.

It’s not Braxton hicks. I’ve been having them also & they feel more like uncomfortable tightening.

Is this normal?

I had diarrhea the past few days so I’m 99% sure I’m not constipated.
