Evening primrose oil??

Va

If you know what it is, I'm sure you know where I'm going lol I'm thinking I should try this out, I'm full term so I do get worry about it. Can someone explain me how I should use it, I'm talking about the other end, how far should I stick them in? I'm preaty scared to put something into my vigina, bug apparently it helps a lot better than taking orally. I know nothing about how to use it
