Ftm need advice!

I’ve been having painful consistent cramping for the last 3 hours, it will fade away for a few mins but I feel like its lasting so long! One will be more intense than the other. Its just so damn uncomfortable, my back is killing me but they legit don’t stop so I can’t accurately time them. It feels like raging period cramps, I can barely walk! I’m 39+3

Not sure what to do!
