C section won't matter unless the.placenta's in a awkward spot. But they should induce you asap.
They should probably do c section.
They should do a ultrasound I had a small placenta and they wouldn't let me.go.longer at 36 wks. It caused my baby to be iugr and he was 3.5 lbs.
the placenta is what provides oxygen and nutrients it collects from your body to the baby through the umbilical cord.
