You know what, with my first I had to switch to maternity pants at 10 weeks. All my other pants were just too tight. i felt silly too, but after talking to my mom, she said she was in maternity pants at 6 wk (: And neither of us are overweight. So it might just be a genetic thing. Now my sister in law is barely starting to show at 18 wks, so I felt very silly. I was showing way early too and it was my first, so I think you're just fine!! Congratulations on the pregnancy.
