bloating?

I am 11weeks and I am just so uncomfortable already, is there a way to make the bloated feeling better? and what about the light cramping the ob said that was normal bc my belly is stretching but does this go away or stay too ? also the extreme fatigue what can I do to help with that ? first time twin pregnancy and I really don't know what to expect or anything any advice would be appreciated I also can't really lay around and rest like a lot of people are telling me bc I also have an 11m old and my fiance works out of town for weeks at a time
