Early Braxton hicks and turnout...

Naloni (birth doula) • 3rd time mama and a birth doula. I am passionate about birth and helping other mamas navigate this glorious journey!
I didn't really have BH's with my first two (or couldve been in unaware). I am 30 weeks with baby 3 and have been experiencing them here and there for the last week or two. 
My Q is, for those who have had other children and had a good amount of BH's early, how did things turn out? Did baby come any earlier than 40 weeks? Did it help get you started well with dilation and effacement?
