Measuring big @ 36 weeks... C section? :(

Colleen • FTM living with hubs and lil Declan Patrick in sunny Florida...
I've been measuring normally all along but today at my 36 week appointment, doc said I'm measuring big. "That's a lot of baby" he said - lol. He ordered a growth scan and I guess I'll end up going in for it this week or next. He said if we're looking at an 11 pound baby, he'd offer a c section. I've been so focused on a vaginal delivery, I haven't mentally prepared for possibly needing a c. Anyone in the same position? 😫 He did also say that baby is in a favorable nestled position for possibly fitting vaginally and that my body will tell us during delivery if it won't be dilating more than 5 cm 😫 now I'm just all nervous!
