Why does it feel like my insides are falling out?

Every time I run I get like insane cramps. Like think period cramps and it feels like my insides are fulling out. I don’t think it is female related because it never changes over the months. I have been running through the pain but somedays it gets so bad I need to sit down before running again. I know cramps and this feels different. Does this just mean I’m weak and just need to run more? Does this happen to everyone?
