I gained an excessive amount of weight during my pregnancy. I started at 5'9 130 lbs and ended up at 197 lbs four days before giving birth, so nearly a 70 lb weight gain. My doctor attributed it to me being underweight in the first place, a big baby (9 lbs), and a lot of water retention during the last few weeks of my pregnancy with my legs swelling up terribly.

I'm now 3 weeks postpartum and am down 33 lbs from 197 to 164, having lost 15 in the first week, 15 in the second, and now 3 this past week, but have been feeling wary about my weight loss. I look like I'm 5 months pregnant with an apparent pooch.

Has anyone else experienced significant weight gain during their pregnancy? Has the weight come off naturally or did it require exercise and diet changes?
