When I had my first, I lost 20 lbs from morning sickness, then rapidly gained it back near the end of the pregnancy. Two years after that, I had my gall bladder out - a nice 8" horizontal incision from just above my navel to my right hip, that cut through several of my abdominal muscles, I think. I now have a wonderful set of stretch marks and a 'front-fanny-pack' from that pregnancy, and an 8" scar. I'll never wear a bikini (unless I win the lottery!).
