Is this normal ?

So about 30 mins ago I woke up from a nap and went to the restroom to pee (TMI) and when I got done the middle of my stomach started doing something weird it was like a dull pain of dragging or twisting lasted about 15 or 30 seconds idk but I never felt it before then i remembered I only ate 2 times today I’ve been eating so much my entire pregnancy so that made me worry 🤷🏾‍♀️ I’ll be 18 weeks Friday … does this sound normal ? or should I call my obgyn tomorrow?
