Im 16weeks and barely showing aswell. Hmm this my second pregnancy and looking like same thing. For my first i didnt show up until i was 7months.
Im nearly 17 wk with my first and im not showing yet either so dont worry :) got a feeling im going to wake up one morning looking like ive swallowed a watermelon!hah
Don't worry, most people just start showing with their first around d 15 weeks or so. Soon you'll be big and wishing your tummy was smaller!
