Help! Water broke?

I am 38+2 weeks pregnant and I think my water might have broke yesterday morning. When I had got out of bed a little bit of liquid rolled down my leg all the way the my knee. I wiped it off and a minute later it happened again but nothing after that. Ever since I've been very light headed, weak , nauseous, have had back pain and cramps. My OBGYN closed till tomorrow morning due to the holidays so I will definitely call them as soon as I can but I was just wanting other people's opinions about what might be going on. I'm a FTM so I'm nervous and not sure what todo.
