You can take both vitex and false unicorn root throughout your cycle. As for some books, it is hard to find anything with all the answers so you may need to seek out a bunch of books. Your local library probably has some you could choose from. These are the ones I own...
Herbal Healing for women by Rosemary Gladstar
herbal Remedies for Women by Amanda McQuade Crawford
The complete Women's Herbal by Anne McIntyre
Infertility Solutions by shana Albo
and one by Karen Bradstreet (name escapes me at the moment)
Herbal for the Childbearing Year by Susun Weed (all Susun Weeds books are excellent!)
Think about taking something for your liver (milk thistle, dandelion root, burdock root, oregon grape root)
