Still waiting on test results but if anyone has experienced this in the mean time

I have been having really bad cramping in my stomach. I’m not on my period and it’s not like period cramps it’s all over. Also I’m having back pain (I know sounds like a period but I just got off like 2 weeks ago) it’s upper back pain. Iv also been having sharp pains in the upper right and left stomach. I’m just very nauseous and bloated and in pain right now and am trying to wait for my results but I may need to go to the hospital. Has anyone experienced anything like this? What was it? I really don’t want to waste their time and go to a hospital for a non emergency. TIA!
