Could labor be near?

Cassandra • 25. FTM.
My due date is today! My last doc appt was Tuesday, and I'm 2cm dilated and 90% effaced! No other signs of labor tho... But! Last night I had crazy dreams, and I mean like 6 dreams! I haven't had those kind/that many of dreams since like the beginning of pregnancy. My boobs have also gotten fuller over night and they are sore again... Could this be a sign that labor is coming soon? Hormone change? Has anyone else experienced this?
