I need help, Should I be worried?!

Hi Ladies... I'm scared & in pain I need a little help. I'm almost 34 weeks (33 & 3) and I've been having bad cramps with some contractions this morning. They aren't regular just painful. And I've been in and out of the bathroom bc of my cramps (I don't have diarrhea, it's almost like normal just slightly softer. But the cramps are painful. What does this mean? Should I be worried?
