water broke??

I stood up, walked to pee, pee came back got undressed and went towards the bed & bam urge to piss and I couldn't stop it. Grabbed a towel & it got wet and fast! Smelled it just to see maybe I didn't pee enough when I went. Had no smell like pee at all. Now I have horrible heartburn, can't get comfy and some back pain. Could I be in labor? Down there just feels sore.
