Labor?

So I woke up this morning when my hubby went to work. I have had leg cramps in my right leg all night and morning (tenderness and can't really walk), and just felt off and not good. So I went back to bed and just woke up and had a mean stomach ache, I pooped three times already today soft stool, and had diarrhea cramps along with it. Now the cramps has stopped and I feel nausea.. Drinking water at the moment hoping I don't puke. My eyes are watering and just feel sick. Could this be labor? Please help..
