labor?

I'm 34 weeks and 7 days. Since last night at 10:30pm I've had contractions, about 4am my constructions picked up and are stronger and I now feel it in my back I've been losing a Brown mucus and since 5am it's been red mucus and I'm still contracting when should I call the dr? I was already 1cm dilated and 70% effaced before this started
