Measuring big!!

Kweilynn
Is anyone measuring bigger than the # of weeks you're actually at? I have measured 3 weeks ahead my entire pregnancy. Today I went in for my 34 weeks follow-up and I measured 37 weeks.. He doesn't seem concerned, just says I'm having a big baby.. I've gained no weight and my belly is on the small side to me. My shower is two weeks away. I'm praying she stays put until after!!!
