I'm 35 weeks pregnant and my baby is measuring around 39 weeks. He's getting too big and the doctor wants to induce me at 37 weeks. I have heard that evening primrose oil can soften the cervix which helps with dilation and effacement. I know it can't put me into labor but could it help speed things up? I don't want to have to get induced by a doctor and I guess my question is, how long would Evening Primrose Oil take to start impacting me and is it worth it? I have 500 milligram pills, how many should I take a day? And I also heard something about taking them vaginally, is that okay as well? I have tried to contact my obstetrician but he hasn't called back. Thank you!
