I don’t know what to do!

I started my cycle 3 days ago, it last a week tops. I normally never have cramps or any other symptoms except the want to eat the whole fridge 🤦🏻‍♀️. Oh & the need to go poop more than usual but I’ve heard thats normal..

but now its not just poop, its the runsssss, & I’m feeling nauseous & it hurts when I move to the side. My stomach growls as if I’m hungry when really it’s probably my stomach crying because its in pain..

I’m not sure what to do, except lay here. I haven’t eaten all day, & due to the nausea I’m afraid too
