Dilation Progress from 1-2Cm

Hi Mommies, ftm here at 36 5/7, na IE na ako ng OB ko and she told me 1-2cm and 50% effaced na ako... ask ko lang sa inyo gano kabilis ung progress ng dilation niyo from the time nalaman ninyo na 1-2cm na kayo? Or ilang days/weeks pa inabot bago niyo mailabas si baby?? Hindi ako binigyan ng Primrose Oil dahil gusto ni OB natural induction.. :) thank you in advance for those who will be sharing.. #firstbaby #momcommunity
