I got a copy of Taking Charge of Your Fertility yesterday, and I have to say, it's one of the most useful and informative books on women's reproductive health I've read. If you can get past the "most people in the medical profession don't know squat" rhetoric, it's a fascinating read. I think I've learned a lot in the past few months about my own body, but it was mostly centered around how to maximise my chances of getting pregnant. This books also provides insight on how our bodies function each month - pregnant or not - and discusses other health issues such as menopause and PMS.
It's the kind of book I would give to my daughter, in my new age Mum attempt to be as open with my kids as possible. It's quite shocking to realise how little you know about your own biology, especially something as significant as your reproductive system. Considering how much of an impact it has on us each month, it's worth knowing that it's more than bleeding, feeling bitchy, bloated, and crampy every 30 days or so.
I would, however, recommend that you keep this book away from your partners. The pictures of cervical positions and cervical mucus are enough to scare them away from your nether regions for a very long time.
