How can I tell if my water is slowly leaking

I’m cramping on and off I’ll be 37 weeks Monday but I’m sitting on my yoga ball to relieve the pain some however my pants are a little damp not much if I put a liner on how will I know if it’s just discharge or my water slowly leaking 🤦🏻‍♀️I feel like this is a stupid question pls don’t tell me I’m not full term I’m aware I just want to know if I can maybe have a better way to tell I’m tired of going in being stuck with needles and sent back home I’ve already had my labor stopped twice I lost a big chunk of my mucus plug when I woke up and have slowly been losing pieces since Monday no rude comments pls
