hope it's happening!

Third time mom. Never went into labor on my own. I am due the 22nd and today I had a bloody show, contractions every few mins (but not very painful), achy back and he has visibly dropped. My last baby my labor was 20 minutes so I'm a little afraid of this baby coming on his own!!! I read online that a bloody show means labor is imminent in the next 2 days. Lost my mucous plug 2 weeks ago and wasn't expecting a bloody show.... So we will see!
