37+5 & no progress at all!

Mi
Anyone else 37 weeks + and baby hasn't dropped yet, no dilation, barely any softening of the cervix? 
My doc said I'm measuring 40 weeks and it's either because baby has not dropped or baby could just be really big to the point that we may have to consider a c-section in a few weeks. 
Really hoping baby just needs to drop. Any suggestions on what to do to help this besides lots of walking & sex?
