Tightness in Stomach

So after I use the restroom and stand up the bottom of my stomach is super tight. As if I was bending my uterus in half and it straightens back out when I stand. It’s slightly painful, but mainly just super tight feeling. It lasts for about 10 seconds and then stops. Is this normal? Literally happens everytime after I use the restroom. I hope this makes sense, idk how else to explain it.
