Hey!! I see you made it over here!! I was the one who recommended you stop by.
Here's what I would recommend.
1. Set yourself up a Fertility Friend account. It's free and it will give you a place where you can keep track of all of your temps and the site will do the work of charting your temps out for you. It really helped me to understand things in the beginning.
2. Pick up a BBT (basal body thermometer) about $10 bucks. You will want to take your temp as soon as you wake up, before you do
ANYTHING else, at the same time every day. Do not get out of bed, do not pee, do not start a conversation with DH... all of those things can alter your temp.
3. Pick up a copy of Taking Charge of Your Fertility. It's the best book out there about charting. There is an ENTIRE section on charting as a form of Birth Control. This book is my TTC Bible! So much information!!
4. Hang out here on the board, read some of the threads, ask plenty of questions and check out our Fertility Charting School. The basics are covered there as well.
Here's a link:

You'll also want to take note of your CM (cervical mucus). That's the BEST indicator of when you are fertile and when you aren't. When you notice that you feel very "wet" or your CM feels slippery like egg whites, that's when you are extremely fertile. Since you guys aren't actually TTC right away, that would be the time to abstain.
I don't wanna overwhelm you with info in a posting... so it's probably a good idea to check out the link for the Charting School and if you've got more questions after that, we can answer them as they come.

again!! We're so happy to have you!!!
