Belly Pic at 15 1/2 weeks

I think you're supposed to do these at regular intervals, but it's hard to know something has changed.

Yesterday, a pair of jeans I have were fitting pretty tight across the waist. But other jeans still fit perfectly fine. I guess I better wear the tight ones a lot--to get my use out of them for a while...
