Suggest Remedy For Itching In Stomach

Ive been getting an itch on my stomache. A little lower my belly button. I've also been bloated and I don't pee or poop much. I don't fart a lot, or a little, I guess it's normal. I am not sure if I am pregnant or if it's food intolerance. My symptoms are related more to food intolerance but I'm not sure. Would you possibly know what I might have?
