Has anyone measured ahead in a previous pregnancy and went on to deliver a full term baby? My first came at 36 weeks via emergency c section and was measuring correctly. We just scheduled a c section for Oct 1st...BUT I went in today for my 34 week appointment and I measured 3/4 weeks ahead. My OB scheduled for an ultrasound at the next appointment when I'm 36 weeks....my anxiety just keeps growing!!! She said either baby is large or I have a ton of amniotic fluid.
