I'm only 8 weeks and 4 days with twins. It's my second pregnancy. I'm trying to hide my pregnancy at work until the second trimester, so I was wondering when you started showing. I feel a little "thicker", and some of my clothes is a little uncomfortable. I just have a feeling I'm going to start showing  sooner than I thought. I'm medium build with a fairly flat toned stomach. When did you ladies start showing with twins?
