Possible bloody show

I had a small clot-like bloody thing pass earlier this morning when I was on the toilet.  Sorry if TMI!  And I've had contractions beginning around 6am that were regular, but now more erratic.  boo!!  I hope they get on a regular schedule sometime today.  I actually skipped DD's dance class this morning thinking that I might have to go to L&D and then they stopped being regular, of course, and less intense. My body is really messing with me this time around.  At least some blood may be a good sign that something's finally happening with these contractions??
