Diarrhea tmi sorry

I woke up two nights ago with major cramping and the sudden urge to got to the bathroom. I went and went back to bed and about another hour I had the same thing. As soon as I releived myself the second time the cramping stopped almost immediately. Prior to being pregnant I would get that every time I had diarrhea which I had in both episodes. I was thinking it was that but I've been getting cramping on and off maybe twice a day the last few days without diarrhea. Braxton hicks? Anyone else experiencing this?
