help! I've been noticing a change

So I noticed that I've been cramping more than usual. I'm cramping before, during and AFTER my period. So feels like now they're constant. I'm also waking up in the middle of the night with poopie cramps. And it's just not normal. I wouldn't have to go poop in the middle of the night unless I was really sick. And I'm not sick I feel fine. So idk what's wrong or if it's normal but I've never experience anything like this before. It's definitely different
