Evening primrose oil after membrane sweep

Ive had 3 membrane sweeps in the space of a week. Everytime my cervix has gotten a little softer but i am still only 1cm dilated... im thinking of adding 3000mg of evening primrose oil tonight before my next sweep tomorrow and another on friday. I am 40+3 and will be getting induced at 41weeks. I don't want to be induced at all and am super scared. Just want my cervix to do something :( FTM
