Cervix pain?

Amy
I've noticed every once in a while my vagina throbs and hurts inside near the cervix. It was hurting like this yesterday and last night. I've checked and its low open and very soft but my cm is dry. According to glow I'm in my fertile time and dh and I have BDed the last three days. Up until today I had been extremely... frisky for three days or so. Today not so much. 
​Has anyone experienced pain and what does it mean? Is it my cervix moving into position?
