Could it have been my water?

Okay so a little tmi. 
I've had diarrhea all morning but don't feel sick otherwise. I have a dull ache in my back and contractions here and there but nothing too noticeable. 
Anyway, I went to the bathroom and peed. Completely finished peeing and then I heard trickling and it was like I was peeing some more but I couldn't stop it. 
I thought it was my water for sure but I stood up and nothing happened. It's been 40 minutes and nothing else has happened. 
I figured it was nothing but idk I have a lot of pressure down there and started getting paranoid that maybe baby is engaged and his head is blocking the rest. I was 3cm and 50% at my appointment last Thursday and I'm 38 weeks 3 days. I've tried calling my doctors office but was on hold waiting for someone to answer for 20 min and got fed up. I don't want to just go get checked because I have two other kids at home with me and my husband can't afford to miss work over nothing so I was hoping for some experiences and advice.
