Home remedies?

Any home remedies for being bloated?? It's bad enough to where my stomach hurts and I have slight diarrhea and I'm feeling nauseous. I can't sleep because of this so I just need help so I can be more comfortable.

I know my period is supposed to be any day now but it hasn't showed up yet. Pretty sure this is one way my body is telling me I'm starting my period very soon.

TIA.
