Help! TTC | Vitex | possible PCOS???

Ive been TTC for a little over a year now. Ive suspected PCOS since i have a little patch of hair growing under my chin& lower abdomen area. But....its crazy because my periods are regular. 24-27 days. I just started taking Vitex in tincture form a few days ago. Have any of you been taking vitex while TTC??? If so how long did it take you to get your BFP?
