Take control of your fertility Toni Weschler ? I found this a really interesting book and helpful in ttc. Not sure about the pcos angle but hopefully there are some ladies out there who can advise. I found this useful in learning about my cycles, temperature charting, things to look out for indicating fertile times of the month.
I agree, I think Taking Charge of Your Fertility by Toni Weschler is really good. It also makes you feel much more in control becaue you understand your body and your cycle much better.
I think you might find it useful from the point of PCOS because (if I understand correctly) your cycles are likely to be quite irregular, and TCOYF will help you intepret when you are likely to be fertile.
I also read a Zita West book - 10Steps to Maximise your Fertiliy which was a good introduction, but didn't give nearly as much detail as TCOYF
