I'm measuring two weeks ahead. But I think my baby is going to be pretty long since my husband is 6'3. The doctor says he don't changing date though until maybe the end. I'm not to limit my weight gain as well. I only gained 16 pounds so far. He is strict on weight gain.
I'm also measuring 3weeks ahead. Because of this my doctor ordered another ultrasound just to make sure that baby wasn't gaining too much weight too quickly. I was 26weeks last week and baby was growing well, she was at 2.2lbs which my doctor said was normal so he wasn't too concerned about my measurement.
