First time mom question!

So I am already 2 1/2 cm I am thinned our and softened. My ob told me today that if my cervix wasn't there my daughter would fall out lol. My question is... my ob told me it's okay to start pumping to speed up the labor process. Does that actually work? I've tried the bouncing on a ball, sex, and spicy foods. But I'm just curious if the pumping would even work?!? If any of you have tips, or advice on how to speed things up I'm all ears. She is sitting so beyond low and I have some cramping and tightness but nothing to record really. I lost a part of my mucus plug today so hopefully this is all good signs that she will be here soon!
