Sorry if this is in the wrong category I just really need some advice 😭

This is definitely the worst period I’ve ever had and before anyone suggests, otc pain medicine doesnt help me whatsoever, I’ve been having severe pain in my back all day long from the back cramps, this is the most nauseous I’ve ever been, if I lay down then I feel okayish I’ll still have the cramps but I won’t feel as nauseous. Anytime I stand up the nausea is 10 times worse and I feel like I gotta run to the bathroom immediately. When I stand up it feels like my sides, stomach and back are being squeezed really hard like it’s a constant cramp that won’t stop, I’m used to bad cramps because sometimes they’re bad but they’ve never been like this. They make me feel like crying, at least with other times I can still get up and walk around, but this time I feel like I need to be on complete bed rest pretty much 🙄. Anyone ever experience this?
