Want to conceive TWINS.

Valerie • 👼Hudson Bennett 11/30/18 @38w+3d
My fiance and I are getting married on 9/10/16. We would like to try for twins. I have PCOS and have been on the pill since 2001. I know coming off the pill can increase my chances of producing extra eggs. I also purchased Vitex (chaste berry) online. Should I stop taking BC after my next period? When should I start taking the vitex (before or after I stop BC)? I wanted to try the vitex before I have to go on clomid, which is a good possibility because of my PCOS. Moms of twins please help!
