Strangely enough, I don't have much of an appetite. I still eat meals regularly but I get very full on relatively small portions, so battling weight gain isn't a battle so much as it is a small skirmish that I've already won. I've seen other mothers-to-be pack on the pounds during this stage so I was a bit worried that my lack of weight gain wasn't normal, but during my last visit to the doctor, she assured me that everything was progressing just fine. Apparently I'm just burning everything I'm eating (despite being too tired to exercise as much as I should be), and the baby's still getting bigger despite my not gaining weight.
The only conclusion I can come to is the fact that my son is slowly consuming me from the inside out, and come D-day will burst forth in a shower of guts and blood ala the chestburster from Aliens. :P
Not actual baby.
Kidding aside, though, I've read up enough on this to know that every woman and every pregnancy is different, and that I should be patient and take things as they come. As someone who's used to planning everything out to the smallest detail, this is a trial in and of itself!
