Cervical Zinger

I get this thing that I call cervical zinger but it's like a sharp pain that happens at the cervix. I've tried finding out information about this type of thing and apparently some pregnant woman get this, but I'm not pregnant. What the heck is going on?! I only got this one time over the last cycle but have been known to have multiple zingers. I'm just curious if there are other woman who have this too and aren't pregnant?! I'm not on any birth control but did have an IUD removed in September.
