the placenta is what provides oxygen and nutrients it collects from your body to the baby through the umbilical cord.
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.
They should probably do c section.
C section won't matter unless the.placenta's in a awkward spot. But they should induce you asap.
