Since the doctor started measuring at around 24 weeks, I have been measuring about 2 cm larger than the number of weeks that I am. So today I measured 37cm and I am 33 weeks so the doctor is sending me for a growth ultrasound. She says the baby is probably right on track but she just wants to make sure. Did this happen to any of you? Anyone end up delivering early because the baby measured big? I was charting and I'm very sure of my dates so I know I'm 33 weeks.
