TMI-Vomit and Pee

Ever since I've been pregnant my bladder seems to have a mind of its own. Whenever I'm sick I can't help but to pee. Tonight my husband questioned why I sit on the toilet and vomit in a bag. I tried to explain to him that I can't help it but he wasn't very understanding of my current situation. On top of that I have the worst gas that I've ever had. I mean the smell alone is nauseating. Is this just me or is anyone else experiencing these or similar symptoms?
