Recommend usage of Vitex for Fertility (such as when to stop in your cycle)

Hello, Hethir! My chiropractor put me on a several supplements to help me conceive, one of them is Mediherbs Vitex. I have been taking it for about 5 or six weeks and after a 93 day cycle I got a positive OPK. I asked my chiropractor if I should stop now, and he said not until a confirmed pregnancy test. I wanted to get your opinion. Also, when I do stop, do I need to wean myself off? Your advice would be greatly appreciated.
