Can BH turn into real contractions?

Jennifer
I'm 37&4...last night I had diarrhea all night with BH all night long. Today I am still having a ton of braxton hicks every 5 to 10 min lasting 1 to 2 min. They don't really hurt just really intense tightening that does not go away with changing my position, rest, or water. Could this be the start of labor?
