Water Broke? 39 Weeks 4 Days

I have a question. So last night i was in the bathroom running my shower water I sat down to pee & I just sat for like 5 mins i stood up to go get in the shower & a gush of fluid started running down my leg & I was like I know I'm not peeing on my self but I just wasn't sure I was already having mild cramping but it was bearable so I laid down after I got out the shower & no signs of anymore fluid came out
