How long did you have regular BH contractions for?

I went to L&D yesterday because I wasn't sure if I was peeing myself or leaking amniotic fluid. Turns out I'm just tinkling. Hehehe. But i found out I'm having regular contractions 5 min apart lasting about 1 min, but they don't hurt at all. I'm not dialated so they sent me home. I am still working full time until 10/20. I hope I make it until then, but getting excited. I was wondering for all you out there...how long did you have regular contractions for until you delivered? Did you have regular Braxton Hix contractions for a long time?
