I lost 15 pounds in my first trimester due to severe morning sickness and I'll be 21 weeks tomorrow. I've put on maybe two solid pounds, and I don't really need to gain all that much weight because I was already overweight (still am, regardless of the significant weight loss)... My postpartum weight might match my pre-pregnancy weight! I'd be so lucky...
