tmi but serious question!?

Courtney
I'm 34 weeks and I've had extreme diarrhea for the past two days. I haven't eaten anything out of the ordinary so I'm wondering could this be an early sign of labor? I've been having mild contractions that come and go as well. I know calling my doctor is an option as well as going to the er but I just wanted to see if anyone else has experienced this before going into labor
