HELPP Advice!!!!

I've been feeling very exhausted today. I've been on zero energy and I haven't been so social with people either but anyways I noticed that my underwear has been somewhat wet. No, it's not discharge. I haven't felt a gush of fluid but Its just a wet feel down there. Its 8pm and really fresh where I live. Theres no way I could be "sweating". I am 31w4d. What would you guys do? I just dont want to go to the hospital for nothing. My SO works one hour away and works night shift.
