I think my water broke but no contractions??

I’ve been trying to decide if it’s my waters leaking or just sweat or discharge.. I’ve been wearing pads all day and whenever I check them they’re a little damp but VERY little..almost dry. I’m debating on calling l&d but I don’t want to go in and waste their time if it’s nothing..I’ve been a little crampy but nothing that seems like contractions..
