Just curious does evening primrose oil help to start labour??

[Excited2meetmyprincess]

I am just curious and not actually planning on doing this myself as I have a c section booked but has anyone used evening primrose oil to bring on labour?
I have heard that it can help start things off and one of my friends was talking about trying it by taking capsules orally. Does it really work? Has anyone tried it? X

I've been taking it since 36 weeks and am now a week overdue. I believe it softens the cervix rather than actually inducing labour, figured it was worth a try but have recently realised that nothing works to bring on labour!!
