Leaking fluid

Sooo when I take my son to school in the morning I feel a small gush that soaks my underwear. I have it a couple times throughout the day but I am on bed rest as it is. Anyone ever have this happen? It’s not discharge, it’s clear and watery. Could this be amniotic fluid leaking only when I am up and walking? I am 33 weeks pregnant and having a repeat c/s. I have a dr appt on Friday!
