36w 5d cramping for 10 hours straight

Around 12pm I started getting cramps, my panties were soaked but not enough to go to my pj bottoms & I broke out into sweat. I also keeo hsving tightening in my stomach. I've changed positions several times , laid on my left side with my legs up & drunk water. I called L&D (as told last week at my appointment, no help she said take a Tylenol). Is this early labor ? I've been discharging since last Wednesday , I'm stationed at +1 & my cervix was letting up. How long does it last ?
