Doctors appointment

Mariana
So I went to the doctor for my 37 weeks checkup and this lady check my cervix and it hurt bad like really bad I never never in my life experienced this and  I went to the restroom like an hour ago and when I was cleaning my self the paper was with little bit of dark blood so I don't know if I lost my mocus plug? Does this mean I can go to labor now?  Pleaseeeeee help
