You know what they say about "usog" ? That sometimes, when you have a good thing going, it's better not to mention it ?
During my last pre-natal checkup, my OB measured my tummy and pronounced baby to be growing as expected. She then told me, "you don't have any stretch marks, that's very good."
Sure enough, just days later, I noticed a whole lot of stretch marks on the bottom part of my belly.
