Pregnant or Too Many Christmas Cookies?

My waist has certainly expanded lately, but I still do not look pregnant. My regular pants are getting pretty uncomfortable, so I broke down and bought myself some maternity pants over the weekend. However, they barely stay up. The doc said I only gained 3 pounds total (as of my 16 week appt on Jan 2) , but it sure feels like a lot more. I will be happy when I look pregnant, rather than just the girl who ate too many cookies over the holidays.
