Chaste berry Vitex!:)

Just ordered some chaste berry Vitex since I read about it online that it could help bring my cycles back and help infertility. In September 2012 I randomly stopped getting a period I went to the doctors end of September 2012 they didn't think much gave me an ultrasound to make sure I wasn't pregnant and didn't see anything so they put me on depo since I didn't want a baby back then. I was on it till February 2014 and got my first period off depo in August 2014. I had another one is January 2015. 6 months apart, I'm thinking my next one is in June? Anyway so I haven't had a period since January, I've been TTC since August but nothing:( I wanted to know if anyone has had this problome or has used chaste berry Vitex and there stories:)
