Cervical checks?

Gretchen
Has anyone had cervical checks? My doctor said she would start them this week (37).  I've heard a lot of people say they can induce labor, and I want baby to stay in until his due date!  I definitely don't want it to start my labor this week!!  We are a little concerned that my hips are too small and turned in, so I wouldn't mind having that checked, but I've never had any contractions or anything.  Has anyone had them? Why or why not??
