soooo I need help.

So I my period has always been irregular . So I started vitex. This is my 3rd period in a row. Does this mean I have a very good change of becoming pregnant this month? I’m 18 , been trying for almost a year, I turn 19 in 2 weeks.. if you ever tried VITEX tell me your story. How did you take them. Did they work more effective while on your period .
