Is it normal that I look more pregnant than I am?

Not really. All women are different and some show early, some late, some get really large in their abdominal area, some do not. Be sure you keep regular pre-natal visits with your dr. And get checked out for any concerns you have. Good luck to you and congratulations.
Yes. Different women have different torso sizes and measurements, as well as different sized pelvises. These differences lead to different appearances of uterine size, relative to weeks of gestation.
