I've always been on the small side and so when I got pregnant everyone was looking forward to seeing me put on weight......which I have (I'm in month 9 now) I actually put on 50 pounds....but people who see me are always amazed at how small I still look (except for the protruding belly of course) So the scale says +50 but I don't look like I've gained that much weight....I fretted many months over the numbers on the scale until I realized that the numbers don't equal fat......there's baby, fluid etc that really adds up too. A friend of mine just had her baby....she had gained 40 pounds total, and by the time she got out of the hospital she had already lost almost 25 pounds of that....turned out it was mostly fluid and water retention.....So my advice is...don't worry about the numbers and just focus on eating as healthy as you can, indulging when you really need it, and most importantly staying happy
