HAHA this is so me. With my second, I was still riding my bicycle to work around month 8, and you couldn't see the bump that well if I was hunched over on the bike+my work shirt, and I was pulled over by a cop (because it was dark, I didn't have my light on) and I got off the bike and the cop goes "....um. you're pregnant." my bump was huge. I constantly got the "are you sure it's not twins"?
