cervix pain, almost 37 weeks

Hard to describe but I know baby is head down and the pressure is significant. Sometimes I get a sharp stinging type pain in what feels like may be my cervix? And the only reason I describe it that way is bc sometimes I feel that same discomfort during a Pap smear. I haven't felt it but a handful of times today. I am having BH (not concerned about these). Just wondering if the pain I feel is bc her head is bouncing off of my cervix
