Did I shrink?

Wow - looks like from the comparison pictures I shrank? Maybe I look smaller because we took this picture in the morning and the others are taken in the evening--belly didn't have enough time to stretch and plump back out. I don't know, but shrinking?? According to how my clothes are fitting, they'd beg to differ. I've moved to wearing more maternity pants, but I can still manage to make some of my regular jeans work...for now.
