Ugh! Not Again...

I've been having contractions again since around 1 PM.  They're getting more frequent and more painful.  I'm trying to do everything they told me too; drink more fluids, change positions, and if I need to, I'll get back in the tub.  Hopefully they'll stop or decrease and we can avoid another trip to L&D.  It get's expensive for them to keep telling us that there are no cervical changes and then send us home.
