Just a question this is my 5th pregnancy but 1st twin pregnancy and all my previous pregnancy weight gains have been different. So I'm asking twin moms is a 9 pound weight gain normal between 2 and 4 months? I went to the first appointment I weighed 146 @ 9 weeks then my appointment this week (I am 16 weeks) I weighed 157.. I don't really eat that much because I'm not hungry like I was with my single babies.. Is that normal?
