cramps

Is this normal? I'm 28w 5d and I'm having period like cramps. No bleeding or anything. They're not bad but noticeable. Also kind of feels like in the lower part of my stomach. I'm a FTM if you couldn't tell haha. Obviously I can't get ahold of the doctor no being Saturday night and Sunday. And not running to the ER if it's not serious and I can't leave no anyways.
