Possible c-section

Mariah

I will be 38 weeks on Monday and I recently had an ultrasound to check the baby’s weight. Baby is already weighing 8lbs 14ounces. My Doctor said that because I am tiny she doesn’t want me vaginally delivering a 9lb baby, so I might need a c-section. When do you think my possible c-section would be scheduled? Would she wait till I actually went into labor or schedule it before my due date? She also did an internal last week and she said nothing was happening and that the baby would most likely come late. This is also my third child and the other 2 we’re delivered vaginally and we’re both 7lbs 15ounces. Also do you think there’s a chance that I could still have a vaginal birth?
