If you menstruate, if you want to get pregnant, or if you dont want to get pregnant run, dont walk, to buy this book! Lisa has produced a truly admirable, well-researched, highly readable resource for women, one that is sorely needed. Mainstream medicine has only recently begun to acknowledge the broader value of the ovulatory cycle and to seriously tackle issues such as endometriosis and dysmenorrhea, and it continues to be limited by two main factors: its complex relationship with the pharmaceutical industry and the institutionalized sexism that has allowed medicine to minimize female-only symptoms. In this impressive book, Lisa works at the intersection of these two worlds, bringing together cutting-edge medical science with the experiential knowledge of fertility awareness/menstrual cycle practitioners to create a vital resource of information and wisdom.
