What's going on?!?

I'm 39 weeks and 5 days pregnant with my first.  Starting yesterday I just began feeling really icky/off.  Crampy, back ache, no appetite, lower abdominal pressure.  I don't think I've had any real contractions, maybe a few braxton hicks (my back starts to hurt then it kinda rolls to front lower abdomen, but only lasts about 30 seconds or so not at all painful just uncomfortable)  Is this labor or pre-labor?  What were your experiences going into labor?  Any help, info, or advice would be awesome!  Oh yeah, and I've been 75% effaced for a couple weeks now with no dilation.
