Bad cervix?

What does it mean when a doctor says that you have a bad cervix? I'm 41weeks and got checked at 40 weeks 5 days I was 1cm dilated and 70% efficiated. I was getting contractions in my back all morning but they weren't consistent. I lost some of my mucus plug yesterday. And if my baby hasn't come by Sunday then I will be induced Sunday. I just wanted to know what a bad cervix means. Does this mean that I'm at a higher risk for a csection?
