My doctor told me for the first and second trimester I don't need to eat any extra calories at all. I have a normal BMi, 5'6 133 lbs. 14w4d pregnant and baby has measured 3 days ahead. I haven't changed my diet and have already gained 5 pounds which sort of leads me to think baby will be fine without adding extra. .. What do you think? Am I going to stunt baby's growth if I don't eat extra?
