I’m 36 + 5 as of today. This is my second child. With my first I was in labor for almost 20 hours and pushed for almost 2. My biggest issue was that I would not efface. Once fully effaced I dilated completely (5 cm remaining) within the hour. I talked to my OB today about primrose oil and he told me he would be comfortable with me using it starting 38/39 weeks (which I completely understand). He also told me about something called gentle birth and wanted to know; has anyone used either of these or any supplements before hand to help with labor and had success?
