average is 25-35 lbs every pregnancy is different. as long as your healthy and your doctor isn't concerned don't worry about weight gain.
Bottom line...u should only gain at least 30lbs during ur pregnancy.
extra 200 calories. that's like an apple lol
Its in the last trimestor u need to have an additional 500calories per day
in the 1st trimester you really don't need any extra calories just eat as you normally would
