Are we in labor? Or is this false labor?

I've been up since 2:16am wide eyed with back-to-back contractions every 3-4 minutes. I have taken a shower, dried my hair and now I am vegging on the couch as we debate if this is really 'it'! Part of me sits with excitement, while another part of me is terrified of what lays ahead - in that I am referring to the delivery part. I have never had so many mixed emotions as I do about the delivery of our child. I feel almost over-prepared and wished I wasn't...I almost feel like it would have eased me a bit more to go in a little more naive.

Update: Turns out that it was a 'false alarm' :( Jess took the day off and contractions went strong all day, but never developed into anything. We are just trying to be patient and know that my body is definitely preparing, however no exciting news yet! My fabulous Mom came up and helped take care of things ~ so it was a fun excuse to get to see her :) Thanks Mommy, we LOVE you!
