Yesterday while checking myself out in the mirror (that is, inspecting the size of my waistline), I noticed that if I suck it in, my belly shrinks to the size it was in July. In July when I sucked it in, it was almost nearly flat. This is how I know that I am getting bigger. Well, this and the fact that my old pants haven't fit for 2 months.
Four pounds gained, not sure about the inches. The sweater I'm wearing today requires force to zip. I need some longer shirts.
The thing I find most amusing is that I can feel the top of my uterus just above my pubic bone; baby is only about 3.5 inches long at this point. As in, not even in the belly yet. So what IS in there making it bigger? :P
