39 weeks today and no real signs of labor?

I'm officially 39 weeks!!! But haven't had any real signs of labor. So far all that I've had is yellowish discharge every time I wipe (Nothing off down there such as itch or smell... sometimes it's a little thick and mucusie), lower back pain (The feeling of a cramp almost, really tense muscles), lightning pain on the sides of my vagina (Probably from her resting her body on my nerves!), and loose poop. But no abdomen pain or anything of that nature! Is this fairly common? I just really can't imagine going into labor and having her within the week. Do you guys think it will hit me all at once then? Hopefully when it does happen I'll be able to tell I'm truly in labor because I don't really get Braxton Hicks or anything. (FTM)
