I'm about to be 14 weeks, and all my pants are a variation of too tight. I'm overweight to begin with (size 14) and I gain weight very easily, especially in my stomach, so I am trying to figure out if I am just getting fat, or if I am starting to show! I do feel a little knot in my lower stomach where my uterus is beginning to push out, but I'm not sure it's large enough to warrant maternity clothes yet!
