Measuring Ahead

Danielle
Hi All, today I had my 31 week appointment and doctor stated my little bean is measuring a few cm bigger than her gestational age. My hubby thought she wrote down measuring at 35?! Has anyone else had this happen? Should I worry? This is my second baby, my son was born April 11, 2009 (one wee early) measuring at 8 lbs. 3.5 oz.
