Weight gain.. -_-

My dr told me that I am where I should be at the end of my pregnancy as far as weight gain goes but I'm not due until Jan. 26th... I've only gained 24lbs (according the their scale in full clothing) only gain 19lbs without cloths on my scale lol I was shocked because I know the normal range goes up to 35lbs.. seems a little early to tell me I've gained too much -_-
