So I posted 2 days ago that my mucus plug started coming away.... yesterday I had a few aches and pains.

Today I have had really bad backache that has sort of started giving me pain and discomfort in my legs. I thought I'd lay down to give myself a rest. And now I am getting period pains coming and going every few minutes or so but accompanied with strange feelings in my cervix it feels like something is pushing against it or stretching it. Am I over thinking things or should I call my midwife?
