what do we think about all this?

Losing mucus plug slowly over the past theee days with a little bit of a bloody show. 
Inconsistent contractions for the past two days.
Fairly consistent 6.5 minute contractions today. 
Lower back pain. 
Consistent lightening crotch. 
What are we thinking? 
I have an irrational fear of going to the emergency room and getting sent home again!!
