I need some advice please!

💕K
So i plan on pumping around 38 weeks, to try and kick start labor or try To process it, but i have some concerns. I know i will be pumping out colstrum, my boobs hurt so bad and i honestly also need some relief. I will be storing it, but my concern is what if nothing is happening and i want to stop pumping. Could that mess up my chances to breastfeed when she arrives? Like could my
Colstum stop coming in or my milk have trouble coming in??
