Doctor talking about c section

Has anyone else's doctor talked to them about possibly needing a c section? My baby is measuring 5 pounds at 32 weeks 3days and says she'll be a 10 pound baby. Honestly so annoyed because ultrasounds can be 2+ or 2- pounds. I don't believe I'll go to full term either way but I want to do all natural 😒 just annoyed c section is against everything I wanted but if it's really needed I will do what I need for my baby girl.
