I wouldn't do it. Can trigger contractions and cause early labor. Ur body isn't use to that much stimulation. Plus you're supply isn't in yet. U may only get a few drops. U got lots of time to pump. Once ur milk comes in, Ull be engorged and can feed baby then pump rest out. I'm on nmbr 4 and nursing my 1 y.o.
Milk don't come in til after the baby the first thing is called calusturum *sorry for spelling* it's the first thing the baby will drink mine is alk ready started to kinda come out with I squeeze my Boobs ... it's a thick whitish color it gives the baby the amuinities and make his/her amune system strong.
I was wondering the same thing and was gonna ask the Dr because they start leaking before delivery so I was just gonna get the pain over with now n start pumping so Its not as bad when delivery comes n they have me start after
I don't think your milk will flow until after the baby is born
