Am i allergic to gluten?

i'm always ALWAYS bloated, my stomach feels like it's just full of gas (i know, ewww). i don't have trouble gaining weight, but after dinner, (usually of rice or pasta), im SUPER bloated...no matter what i eat my stomach hurts...i don't know if this means im allergic to gluten but maybe it is....its not just after dinner that ill bloat. is there a test or something my doctor can do?
