I'm a ftm and I'm 31+3 with a baby boy.

Since yesterday morning, I've been very crampy and in pain. Idk if I'm having BH or what it is but I am having (very similar to) menstrual cramps. Or the cramping you get when you are gonna have diarrhea (which I don't have, actually constipated a bit).

And then every few mins I get this sharp burning pain in my vag or I guess my cervix. It lasts anywhere from a couple seconds to more like 30-40 secs.

I have an appointment next wednesday on the 31st. Baby boy is not big for his gest. age or positioned weird. He's exactly the size he should be, albeit a slightly bigger head thanks to his dad.

I just wanna know, should I be concerned or is this normal?

Bub is still moving, not kicks or punches but full body rolls.

Any insight is very well appreciated.
