38 weeks 4 days .... should I know?

Should I be able to know/tell if I have dropped, thinned, or am dilating??? 
I went to my apt last Friday at 38 weeks and was still "-3" (high up) , closed (not dilating) , and not thinned.... 
Doctor wants me dilating by my apt Friday (in two days) so she can induce me on Monday due to her leaving for vacation and complications I have had throughout pregnancy...
I have been :
Bouncing on excercise ball 
Taking evening primrose oil 
Eating pineapple
Walking on treadmill 
Sex
Nothing is helping and Idk what else to do...
She still needs to drop more I think and I'm so worried that when I go in I still will be closed....
Should I be able to tell if I have dilated or thinned? 
Can I dilate and thin and not know it??? 
I don't feel any different or have had any changes...
