36 week ultrasound!

KK

so I went for my 36 week ultrasound today. baby's head is measuring at 40 weeks, body is at 38 weeks. They said he is already 7.4 lbs. I guess so much for my hopes of having a peanut! they're sending me for another glucose test to make sure I don't have late set gestational diabetes since he's so big. Has this happened to anyone else before?
