Severe lightning crotch?

Quick question: has anyone ever had this weird sensation like you were getting stabbed in the cervix with a knitting needle? Instead of the pain shooting down my legs it shoots up towards my belly button. I’ve had it happen quite a few times today & every time it happens I stop dead in my tracks & double over. It’s so sharp! 38w3d. Was 1cm dilated & 2% effaced at my appointment 4 days ago.
