Time? Maybe?

I've been having on and off Braxton Hicks (practice contractions) for the past month now.. they are painless, short and just feel like a muscle tensing up. The past two nights, they have become a lot more frequent and regular, but no pain. This morning however is a little different. The contractions are definitely not comfortable now and have become regular ~20 seconds long, and roughly ~8 minute interval apart. Hence, I am up blogging this since I can't go back to sleep. However, this is still considered irregular and not labor yet... so, now we just wait and see.
