What do you do if you go to the bathroom but you cant go?

If you feel like you need to go to the bathroom, But don't go, Don't worry about it because it might just mean your stomach hurts, Or is gonna hurt. It also could mean that the poo or pee isn't ready to come out. Or you just haven't ate anything in a while. It does not damage, Or cause anything bad.

Or your constipated because you ate too much mexican food and you just need some fiber to push out the poo. or you need to have some asparagus cause it makes you pee
