Baby's head measuring large

I just had an appointment with ultrasound at 32+1 and doctor says baby looks healthy but weight estimate is around 5 pounds and head is measuring large. Head looks like it's measuring around 36 weeks but he says it's nothing to worry about. Now there's talk if he continues getting way bigger to induce early or have a c section. This kid is writing checks my vagina can't cash! Anyone else having a big headed baby?
