Baby will be dropping into the pelvis.

My boy was always Measuring about a week behind on fundal height and then dropped a little further behind at 38 weeks. He was born at 39+2 weeks and was a generous 9lbs 3oz!

Fundal height is stupid, it just causes unnecessary stress. My daughter was always about 6 weeks behind and was born 7lbs 9oz.

It all depends on babies position, your own height and body structure .... Everything will be fine with your baby. Im sure its just readying itself for its grand entrance!!!
