Don't worry, this is happening to me too, the dr checked me twice and it wasn't my water...it's just the discharge
At 26wks you'll have a lot more discharge onwards. I'd say thats what it is!
If you let it air dry on your fingers for a brief time does it go slightly sticky?
It just sounds like discharge to me. My sister in law insisted her water broke on 3 different occasions... it never did.
So go get checked then if you're worried.
