Am I in early labor???

Laura • I am 25 years old and engaged to the man of my dreams. We are looking forward to meeting our daughter on 03/20/2015!
I am 3 days past my due date and for the past 3 hours I have been having contractions. They have averaged about 50 secs with about 5 mins apart. I took a bath and they stopped for about 20 mins. Then they started again and kept going 5 mins apart. I haven't had one in 20-30 mins. Am I in early labor or is this just Braxton hicks still??
