35 weeks and about 1 cm dialated

Doc said as long as baby stays in til 37 weeks it's okay to have him after since they will induce me anyway. I purchase evening primrose oil 1000mg capsules. I do not want to vaginally insert so how many should I take orally? I did not ask my doc about taking them I'm almost sure she would advise against it just bkuz she advises against almost everything. So hoping to just thin my cervix slowly bkuz it's still 0% effaced and I'm barely a 1cm a small 1cm.
