I found this website really helpful in directing me to other websites, books and papers that had very relevant information to the topic at hand.
www.gardenoffertility.com – Katie Singer’s website is a resource for purchasing Fertility Awareness books, downloading charts and getting a broad understanding of Fertility Awareness.
www.fertaware.com – This is the website of my teacher Ilene Richman. She works out of NYC offering FA consultations. Her website is a fun and thorough resource for becoming familiar with Fertility Awareness.
www.poriutivit.com – This website is mostly in hebrew. It is a resource for anyone wishing to learn about Fertility Awareness in Israel.
http://www.contraceptivetechnology.org/table.html – Table of effectiveness rates for various forms of contraception.
