gassy...

For the past few days, a week I believe. I've been super gassy, and feeling like I need to poop. I don't poop a lot. Usually I go once a week, sometimes once every 2 weeks. That's normal for me. But this past week, I've gotten really gassy. I can't hold in my gas anymore. It seeps out and smells like complete crap. I don't know what's wrong with my body. Or why it feels like this. Please tell me I'm not alone.
