Was this my water breaking?

So I went to the bathroom normally ya know and then I was standing at the mirror after in the bathroom and then I just "peed". And that's never happened before. It wasn't like a whole pee it was just leaking but I couldn't stop the leak. It was a good amount of whatever it was. And I think last night I lost my mucus plug but not all of it because there wasn't any blood in it. It was just a big glob of green booger like stuff. I'm 38 weeks and 5 days. And the baby really hasn't been moving like he normally does but when I went to the doctor yesterday she said that maybe he was getting ready to come and I been having really bad BH contractions for a couple weeks.
