Icky "Morning" Sickness

I've been nauseous off and on for the entire pregnancy so far, but no throwing up. Until today. I came home at lunch and caught a whiff of SOMETHING (who knows what, it was just something stale smelling) and it sent me into gag mode. I did my best to convince myself that I was NOT going to be sick, but I ended up giving in. I'm just glad I hadn't eaten lunch yet. That would have been so horrible.
