Do you think??

A
Pumping will start my labor ? My baby is measuring big I don't want to be induced. Has anyone had it speed things along ? Or know if anything I can do to speed it along ? 
*** ⚠️ I will not try castor oil ⚠️ *** 
Also not asking for advice on whether or not to try to induce my labor....
Naturally at home not through c section or medication !
