7.5 hours. I laboured at home and ate breakfast, took a nap, barely made it to the birth center, and delivered 20 min after arriving.
Miscarriage, I laboured for 2.5 hours and had one large push to expel the placenta in whole.
Expecting my 3rd and I have a feeling it will go even faster than the first!
My experience was to use visualization of being relaxed and open. I rode each contraction through, instead of fighting it. And I kept my lips and mouth relaxed by singing through each contraction. It was primal, but it worked!
