Chest and abdominal pain

It's late at night, no doctors are open around here, and I'd really rather not go to the hospital so I thought I'd come here to see if anyone here can take a guess at what's wrong with me.
I'm 21 years old. No health problems that I'm aware of. A few hours ago I started experiencing cramps, nothing too crazy and I have just ended my period so I didn't think much of it. I took ibuprofen hoping it would help. But now, my entire abdomen is killing me. It hurts to sit up or stand. Still cramp like in nature but all over. And I keep getting sharp pains in the middle of my chest whenever I move or take a deep breath. I feel somewhat nauseous as well. Has anyone ever had this happen to them? Should I go to the hospital?
