Has anyone’s water broke early because of a big baby or a lot of amniotic fluid?

I am 36 weeks and my doctor thinks my water will break from the pressure of my baby being too big/having excess fluid. I have a csection scheduled for the 25th of June but he keeps making comments about how he thinks I won’t go that long and it’s making me nervous. Having the extra fluid makes it so I’m more at risk for some complications if my water were to break at home.
