women who do Evening primrose oil vaginally...

Kierston • Married to my bestfriend in Hawaii, waiting for our baby girl ❤️🎀
Just got my first bottle. Almost 38 weeks in a couple of days. I read where a couple of women inserted like 4 into the vagina and went into labor 24-48 hours later..
I was wondering who has tried it, done it etc and what are your thoughts on it. Does it work? 
Already 1cm dilated, 50% effaced and -2 (this was 4 days go)
