Hi, I'm currently 28weeks but fundal height measuring 37 weeks. My belly went crazy at about 24 - 25 weeks and I was diagnosed with polyhydroamnios (excess fluid). Apart from being a little more uncomfortable than normal I think all will be fine with both bubs and I. I always measured a few weeks bigger than dates with my other boys and they were born 8lb2oz and 10lb so who knows - wait and see.
