Medium to Heavy flow of watery discharge

Not sure if I am paranoid, but would like to ask fellow mummies or experienced mum if you face the same issue. I am on week 31-32, this is my 3rd day experiencing med-heavy flow (I’m using a regular pad) to hold the watery white discharge. Have contacted my Ob for an appt, but it’s ltr this week. So trying to get some sensing here. What I worry is - whether my water bag is leaking? Thanks in advance! #advicepls
