Pelvic size & vaginal vs. c-section

I had a doc appt today and I asked how will I know if I can have a vaginal delivery or csection for my size. (Obviously some things are unplanned).

The doc said for my size my baby girl is already a big baby and she’ll be at least 7.5 pounds (current estimate).

And they will measure my pelvic when I’m closer to 37/38 weeks!

Is anyone here petite like me and has a big baby? What kind of birth did you have (if you had no complications).

I’m 4’11” and now 145lbs.

Pre pregnancy I was about 127.

I’m 33w5d today.
