Hey biggiwant girl,
Yes, please consult a doctor so that you can get a suitable BCP for PCOS. If you can't do that locally, there are online BCP prescription/consultation sites like Nurx. It's super important to get your PCOS under control before NBE can start to take off! Androgens *strongly* inhibit NBE, even if you take P & E supplements. I think that might be the major reason why your program did not work so far. And the pills are safe to use if you get them from a trusted source (registered pharma).
I'm looking into mitosis, alveologenesis, and the prolactin pathways so hopefully I can come up with more info soon. You can also look at my previous posts on BO and PM (deoxymiroestrol). Mitosis happens in luteal according to the article I posted.
