Laying in bed and belly "hurts"

FtM2b and usually at night the last couple nights. My belly has felt crampy. Not like period cramps, not shit cramps, but more like I've been running cramps. It's last for a while. Like I can notice it for over and hour or more. Should I be concerned?

I'm 23 weeks.

During the day I don't notice or feel any different.

I know ultimately a doctor would know best but I figured I'd see what you women have experienced similarly or not.

Like I'm going to assume either Braxton hicks or like possible gallbladder or something, which a doctor would have to confirm.

Come on ladies put me at ease so I can sleep :)
