I have a great book on the timing/cervical mucus/temperature thing, I would be happy to send it to you free of charge. I know it is effective in planning pregnancy, as I got pregnant 3 times using this method, and I imagine if I didnt want to become pregnant, I could have used the same symptoms to avoid it. In fact, the book is called "your fertility signals: using them to achieve or avoid pregnancy naturally"
My husband moved out last june, so I have no need for prevention and no opportunity for pregnancy
Anyway, it is written in a very easy to follow style, and has charts and other references to help.
Also there is a software program you can download called cyclesoft...if you email me, I can get it for you. I think its kind of neat...it tells you by the info you put into it, when is the best time to have sex if you want to get pregnant, and when to avoid if you arent interested. and its FREE...my favorite price
