Vitex chaste berry......

Kristina • I am a mother of 2 and ttc our 3rd. I have 2 businesses. I am a photographer and a distributor for It Works wraps.
Hello! So I took vitex in 2011 (nov) and got pregnant with my daughter in 2012 (feb).... I am ttc #3 and back on vitex... I am taking 2 tablets in the morning and have been taking it since Friday (8/28).... I haven't had a period in a while and I started TODAY (8/31) ..... has anyone taken vitex and had it work pretty much immediately?
