Baby still needs to drop into pelvis?

Amanda

Hi! 
I'm 38 weeks tomorrow. I had an OB appointment Monday. When the Midwife checked my cervix, she said the outer portion of my cervix was dilated but the inner part of my cervix was closed but soft?  She said she believes that baby’s head is still high up and I need to do exercises to try to get baby to drop down in my pelvis. 

Anyone else ever been told this about your cervix? If so, when did you go into labor? And what exercises did you do to help?
