Real or prodromal labor?

Hey, ladies, it's my due date! I never thought I'd be in labor exactly in my due date but Last evening I started having contractions. They were kind of all over the place but continued throughout the night and all this morning. I kept waking up to contractions and had more bloody show (originally had it on Wednesday) around 2 am. The pain isn't toooo horrible (like pretty bad period cramps) and they're usually between 5-8 minutes apart, but every once in a while it's more like 10 minutes apart. Is this the real thing?
