Pumping?

Hi! I’m 38+5 and am beyond over being pregnant! Don’t get me wrong, I love feeling my baby’s kicks and love having her close but I am miserable. I can’t even walk without wanting to cry. The weight of her in my groin area is just way too much. I’m already at 3cm but I have been at a standstill for a week. I’ve tried sex, walking, squats just about everything. The one thing I haven’t tried is pumping. Would it be okay if I tried pumping? Has it worked for most of you ladies?
