trying to get baby to drop 😔

40 weeks and my baby has dropped some but she is still high. Not even dilating. Doctor wants me dilating by Friday. Been bouncing on excercise ball, starting walking on treadmill for 30 minutes, and taking evening primrose oil.. 
I feel like I'll never drop and I'm so worried I won't be dilating on Friday. 
I can't even tell if I have made any improvement this week... 
Any advice :/ 
Can I drop and not even know I have? 
I don't think I can dilate if I haven't dropped all the way? :/
