when will gas stop????????

I'm so done with it !! I thought it was a first trimester thing but week 17 and here I am all bloated and gassy! Is there anything I can do to stop it? I don't know how to keep on hiding it from my DH, I know it's natural an everything but is the most un-sexy thing ever so I don't want he to see me that way :( posting anonymously because I'm seriously embarrassed!!!
