Baby's head still floating?

Okay so I just got back from the hospital and they said I was having contractions and they were 15 minutes apart. But my baby's head is still floating and im not dilated because of that. I cant stand this pain its soooo terrible so I was wondering what I could do to get this process on the ball...Im 4 days over due. And is it possible to not be dilated and have contractions be oh I don't know like 5 minutes apart?
