Hello. have you used vitex before? the reason I ask is that in some people it can do more harm than good.

Have you tried false unicorn? its a little pricey at $50 per jar but very effective in maintaing a perfect environment for conception and works hand in hand with vitex.

Also I believe in taking evening primrose oil before ovulation, and then fish oil between ovulation and the end of your cycle.
There is a great website called "fertility naturopath". If you google that, there is heaps of information and also plenty of FAQS.
