How do you use primrose oil to soften cervix?


First, how much do you insert? And when do you start inserting in the vagina to soften cervix?

Have any of you ever done this? Did it help? Does it feel weird??

I’m 35 weeks and just preparing.

I have already started raspberry leaf tea and dates (which I’m having a hard time eating 🙄)

Anything else I can do to prepare?
