I have the same problem! But I think its just pee since my pad only gets wet on the top and not the middle. You could try using a paper towel also, its a little easier to tell which part gets wet.
I've been having the same problem. I went to doctor and he tested and it was not my water.
If you can't control the flow it's your water.
I ended up going to the hospital to make sure it wasn't my water. They said it was just more of the mucous I guess. I left there around 8pm and came back at 1am because my water actually broke!
