Lots of leaking

Have any of you had this experience? This isn't the only chair I've done this too. I've been to labor and delivery but they said it wasn't my water. It's my second pregnancy I'm 37 weeks, I had a lot of discharge with my first but not so much that I'm leaving stains😑😑 my step b was negative and I know it's not an infection. I'm just so confused. Could it be amniotic fluid??
