Baby measuring 2 weeks ahead

Chaya

At my last appointment 2 weeks ago the baby was measuring 1 week ahead. Now at 34.5 weeks, baby is measuring 36.5 weeks. I am never feeling well, so uncomfortable and now I’m stressed that baby will be too big and I will need a c section. Has anyone had experience with this? They scheduled an ultrasound for me in 2 weeks to check the babies growth better.
