I'm 37 Weeks Pregnant And This Is My First Pregnancy

I'm 37 weeks pregnant and this is my first pregnancy so I really don't know what all to expect as my due date gets closer. I really had to use the bathroom and I held it for a little bit, not too long. I went to the bathroom and when I got up I noticed my underwear and my pants were a little wet. I assumed I had just peed myself a little bit but I didn't feel myself pee at all until I was on the toilet. So (gross) I smelled it, doesn't smell like pee so, am I leaking fluid?
