Cramping=possible cervical change?

40+2 today and we managed to have sex this morning (extremely slow and short, so I wouldn’t be sore from that) and I’ve felt kinda crampy ever since.

I’ve had contractions on and off the last week but this is different, it’s not tightening and it’s low in my hips.

I’ve heard that period like cramping can signify cervical change like thinning and dilation—can anyone confirm?

I have a midwife appointment tomorrow since I’m overdue, so I’ll ask then too of course.
