Questions about vitex

Hi everyone,i didnt know where to post this but here it goes,i just wandered if anyone has any proper info about vitex or has been on it and conceieved without any probs.I have been on since jan(when i came off the pill)and i heard it was safe and you can take it even in first few months of pregnancy and then yesterday i spoke to a naturopath where i get it from and she said not to take it if im actively ttc.So as you can imagine im totally confused!!!She said that she wouldnt recommend taking anything(except prenatal vitamins)whilst ttc because of the high possibility of falling pregnant and taking certain things like vitex isnt good.So i just wandered if anyones heard similar or been on it while pregnant and been ok,i just dont know now if i should keep taking it or not.Thanks for any info!!
