I'm 13 weeks into this venture and I'm a little concerned. I've had 4 pregnancies before this one, and I've lost weight with all of them, it's my normal, but at this point, I've lost more in 13 weeks than I had at delivery with each of my others. (3 kids at home already) My Doctor doesn't seem concerned, after all, I have lost weight with each of my others, and he's been my OB since my second one. I think I just want some encouragement...
