"back" labor?

So, I've been having really terrible back pain since last night. It used to only do it when I was laying down and now it's just coming in waves. Its also accompanied by my belly getting really, really tight. I'm drinking water, but the only thing that makes it ease up is getting on all fours. I can't even walk around to get it to go away. Never felt pain like this so it makes me think it might be contractions...haha.

Do you guys think this could be early labor? I'm 38 weeks tomorrow and I'm about to start timing them as I type this.  I have a doctors appointment at 3, so hopefully they'll tell me more.

 Just wanted some opinions
