Mommies, please help and answer this for me!

I'm 37 wks pregnant now and for the post few days have been cramping and having lots of bh contractions. This morning it is so so much worse really bad cramping that feeling like I need to poop (sorry tmi) I've gone to the bathroom so many times, ugh. And I'm still having the bh contractions. Nothing so far has been timeable, but painful. Is this just normal for this sage? or what's going on? help, I never made it this far with my first.
