It's important not to push before the cervix is fully dilated. Pushing too soon can cause the cervix to swell and become less dilated or could result in damage to the vaginal canal. However, this does not mean that you have to consent to a pelvic exam. An experienced professional will be able to assess your dilation in other ways. They can observe your behavior, the frequency and length of your contractions, and the position of your purple line.
