When will I feel pain?

Sammie • Hubby and I are expecting our first miracle! Avonlea Janine on 8-8-15!! So excited!
I'm 38 weeks pregnant...of course I've had normal pregnancy pains like major siatic nerve irritation, pregnancy induced carpel tunnel syndrome, trigger thumb, loss of voice due to the massive amounts of edema...but I've never felt a painful contraction. All my pregnant friends say they started feeling Braxton hicks become painful around 34-36 weeks. My Braxton hicks never hurt. Just mild muscle tightening. 
I joke and say that maybe it means I won't feel any pain during labor lol. But just wondering if anyone else never experienced pain until true labor began??
