Evening Primrose Oil

Katory • Just patiently waiting for the arrival of my sweet baby boy 💙💙 11/29/15
So I'm 39+1 and I've been 1 1/2 centimeters for 3 weeks now. I've heard some good about Evening Primrose Oil and it helping soften the cervix. I'm leaning towards going to get a bottle. Any other mommies out there tried it? And was it successful??
