I am 31 weeks and 2 days as of today. I went to the Dr office and I am measuring at 27 weeks , not 31. Due date was changed from Oct 21 to Oct 30 because of the babies size. Is everything ok I wonder? I asked my Dr but she gave me a look like I didn't need anymore stress and ordered another U/S. What to think .. I am not gaing wieght either , not much anyways .. 3 lbs in a month.. 3rd Child .. this doesnt feel right.
