vitex Help !!!!

Tamar • Just waiting on my bundle of blessings im 34 married for 11 yrs
I started taking vitex to start my period 7 days later  I got my period ended after 5 days but I noticed later that day I had some breakthrough spotting it's been 2 days and I'm still spotting very light is this because I'm not taking it my whole cycle and should I just start back taking it now or wait till I think I should ovulate and from there keep taking it my whole cycle has anyone else experience this it's kind of irritating especially since hubby and I want to due the due soon lol
