I've had this weird pinching feeling up at my cervix a couple of times today, enough to make you catch your breath

The only other time I've felt anything close to this is when you have a smear.
It doesn't hurt when I pee and there's no blood or "funky" discharge so I'm not worried about infections or anything but I'm wondering what it might be and if anyone else has had it too?
I don't want to keep bothering my midwife with trival questions for you guys are the next best thing
