Water breaking?

I'm a FTM and slightly confused I'm 38W2D. Last night my fiancé and I were doing the good do. Right after he finished and I was about to get off him, I felt this urge to use the bathroom. But before I knew it, this liquid starting coming out. I couldn't stop it. It soaked up a pretty decent size of our sheets and little puddle on floor. It was clear with no smell. I haven't had any contractions and it's been little over 12 hours. I have gotten pains though throughout the day, best way to describe it is when you have to go #2 and you have to hold it and you get that cramping lol. Followed by pressure and shape pains down there. I have had extreme back pain, but I also suffer from back problems so I can't really determine if it could be back labor. It is worse pain than usual though. I also have this little watery discharge since this morning. May sound bad, but I just don't want to go to L&D and it not be my water and be embarrassed for peeing myself🙁
