Sleeping woken up by a little gush

38 weeks and 2 days. I was dead asleep and woke up to a little gush of liquid. Not a ton or anything. Just a small amount. I went up to go to the bathroom and came back to lay down. Now I’m wondering if my water leaked or if it was something else? I didn’t have to pee or anything? I plan to at least check in with my midwife when they open?
