Primrose oil

I had some issues with high blood pressure though it was normal at my appointment today. My obgyn doesn’t want to induce unless we have to and if things take a turn. He said he doesn’t want me to go past 39 1/2 weeks though. He did say he wants me to start taking primrose oil to try and soften my cervix since it’s nowhere near ready. I’m 38 weeks.

Of course I googled and there’s a lot of bad articles on primrose oil and the potential complications. I’m scared to start taking it. Does anyone have any stories/advice on this? I feel like if the obgyn mentioned it then it must be safe right?
