Oxymoron?

So, in exciting pregnancy news, I've lost 12 pounds.  I'm super excited about that little tid bit!  And I've consulted the internet/pregnancy books and it is normal for women to lose some weight in the beginning of pregnancy, especially if they were overweight to begin with or have really bad morning sickness.  Well, I haven't been throwing up, but I've been very "regular" if you know what I mean, and I've had zero appetite, and the doc thinks I'm healthy, so we're going with it.

However, most of my jeans are too tight.  This blows my mind.  In the past, when I've lost a few pounds, my pants become loose.  However, it pains me to button a few of them.  I'm not quite sure I'm showing yet, but maybe I am and just can't tell because I've lost my "fat" but replaced it with "baby" and it's all evening out?

Who knows.  Pregnancy is weird.
