If you go to fertilityfriend.com, they have an awesome charting system that you just input your daily temp each morning and they do the chart for you. I highly recommend charting, it gives you an idea a day or 2 before AF if you're pregnant or not because if your temps start falling, you know AF is on her way, but if they stay high, it's your first indication of possible pg! Plus, it's neat to see them coincide with your OPK's---if I hadn't been temping I wouldn't have known that my body didn't O the first time it tried this month.
Good luck! Let me know if you have any other questions!
