Just bought evening primrose oil- now what?

Question

Im 39wks. Is it best to take it orally or insert vaginally? Ive a bit hesitant to take it just cuz ive heard both sides of the fence saying it could be harmful but that its also helped so much. So not sure. If i do decide to take it, how much do i take at a time? 
Just trying to decide if this is something i should do or not. I dont want to do anything drastic to rush baby but im 3 days away from edd and theres zero progress. Still high up and closed.

Answer

I drunk rasberry leaf tea towards the end of my 3rd trimester as it was recommended by my midwife,my daughter came two weeks early and was a healthy 7pound

Answer

I'd take it vaginally before bed. It'll ripen your cervix quicker that way.

Answer

You can take it both ways. I did what the both recommend orally and one vaginally at night. Idk whether it helped or not I had a really tough labor

Answer

I started taking it at 37 weeks. I would take one pill orally in the morning and then one pill vaginally at night. We're a panty liner though because you will leak it out!! Worked great for me!
