Whenever I have been pregnant I have severely hated being in a room, or area where people fart, they literally make me vomit...?
I have to cover my face, I have no idea why, although I dont hunt them out when not preg I'd always prefer not to sniff any, but when preg I feel sick when I hear one or smell a silent one, I have to cover up my face so I dont induce any!!

Also diesel, our Aircon at work broke & near my office they've put a diesel machine thingy & it's making me ill!!!!
