Water breaking/leaking?

I woke up in the middle of the night and my underwear was soaked and it was on my legs it didn’t get on the bed so I thought maybe it was sweat or maybe I peed on myself (joys of being pregnant). I’m 38 weeks and a week ago I was 3cm and 50% thinned. I changed underwear and put a pad on and I have a little bit of leaking slowly. It’s been 3 hours and I’m not having any contractions just some slight cramping. Could it have been my water breaking?
