Mucus plug? Water leaking?

I’m 38+2. I was just in the kitchen making breakfast and felt a warm gush. Not enough to run down my legs but to completely soak my underwear. They are wet with fluid and this also came out. How can this just be this much simple discharge? Or could it be my water leaking?
