WHAT?! HAVING A BABY RUINED MY BODY I'm 5 "2 and am in a heathy weigh range for my age and height. I weighed 155 at the very end of my pregnancy 140 1 week postpartum and then from there it fell off. I retained a lot of water weight. For some people with age and height 140 -150 is a healthy weight so don't take my information to heart for you
