Disappointed (csections moms)

So I just left my perinatal appt, and this is my 2nd baby. Apparently I'm measuring ahead. Currently 23 wks, but measuring almost 28 wks. I had my first son via emergency csec almost 4 yrs ago, so disappointed my ob already deciding to schedule me a csection if baby is too big, I was already deciding to do a vbac with this one... Any csections mom that delivered naturally a big baby after being told their baby was measuring big ????
