evening primrose oil

I'm 37 weeks now. Kakabigay lang ni OB nyan 1 week ko narin take. Last visit namin open na cervix 2cm palang pero makapal pa cervix, bngyan ako nyan pampanipis ng cervix. Orally ko po sya take hindi po insertion. Food supplement lang po talaga yan pero ung main ingredient kasi nkakatulong mgpanipis ng cervix. Para po syang myra e
