Anyone heard this?

Today I went to the er worried about having a uti. Well the nurse who did a pelvic exam was doing her thing and then she says "sorry I had to pop out your cervix" has anyone ever heard this before?? None of my girl friends have heard it and they have kids as well! Mind you my period is 10 days late and when the urine came back negative they refused to let me do a blood test so I was already upset.. Any help would be very appreciated!
