gas during pregnancy

i can honestly say that i was never the type to fart in public.  i didn't tend to have gas and if i did, i always let it out in the bathroom.  if i'm in a public restroom with several stalls (and i know they're occupied), i tried not to fart then either.  i kept that stuff private.  but that's no longer the case now that i'm pregnant.  i fart everywhere.  i admit that sometimes i let it out to make me feel better.  but most of the time, i just have ZERO control!  i share an office with another girl at work and the other day, i farted and it was not a silent one.  not a super loud one either but i wonder if she heard it?! i was watching tv with mik tonight and i accidentally farted... and he heard it! i immediately had this guilty look on my face. can't even hide it! oh well, there's a first time for everything!
