Am I imagining things?

So I am totally rocking the first trimester blump and have a nice jiggly layer of pudge below my belly button. But farther down, about halfway between the layer of fat and my pubic bone, I swear, it feels firmer than it used to. Obviously, I know how small my baby is and that it's impossible to actually be "showing" per se, yet, but do you think it's possible to already be "filling out" that area internally, to the point where it would feel firm from the outside? Or am I just off my rocker and imagining things?
