Ok so this is my second pregnancy I never went thru this with my son. Well today at my regular OB appointment I'm 31 and half weeks but my uterus (fungal height) measured 34 weeks. Just two weeks ago I was measuring right on track at 29 weeks. So my ob schedule a growth ultrasound at my next appointment. But my question is why could I be measuring so far ahead all of a sudden? Could my baby big bigger then I think? Have this happened to you before? What was the reason you was measuring ahead?
