Lea thats a good idea.. i might start measure my tummy too. Ive noticed some of my old work pants dont fit anymore but thought i could just be getting a fat butt.. but then everyone at work says from behind i dont look any different (thank god!).

Meg- My friend (that use to work with me) is the same! She is 6 weeks pregnant with her second and came into work the week before last when she was only 4 weeks and everyone was asking me if she was pregnant.
And then ive heard stories of people who didnt know they were pregnant until they went into labor. I think youre right, everyones different.. i started showing at 10 weeks and this is only my first.
