Am I In Labor?!???

I Am A FTM 39 weeks pregnant I Started Having Brown ish stuff come out yesterday early in the day but was having no contractions. At 12:00am in the middle of the night I started getting contractions but was feeling more like period cramps . Its been since 12 and im still having contractions but now more towards my lower back. They are5-10 minutes apart lasting1 minutes since 12:00pm today. The pain has now been worst I dont have no more bleeding nor no leaking of any short just lots of urge to pee after every contraction. Should i go to labor and delivery or still wait it out? Please help...
