My wife is 37 weeks pregnant and her platlet count is at 100, at what number does she have to get induced, and is vaginal delivery safe or is c section?

Low platelets: This is called third trimester gestational thrombocytopenia due to the peak effects of the placental hormones causing fluid retention and subsequent dilutional low platelets.Nothing to worry about do not let her obstetrician give her any steroids trying to raise her platelets since this will predisposes her for eclampsia. She will be fine and do not worry.
