When you get the hang of charting to conceive, it is an easy to apply and fairly straightforward method that determines the best time to conceive. Some women don't like having to set their alarm earlier to take their basal body temperature, and the fact is that taking your temperature in a state of passivity offers more accurate results than taking your temperature during the day, when you might have been running around.
Others don't like the idea of tracking their cervical mucus, something that is often associated with fertility charting. If you have decided to take the plunge, though, ovulation tests basically become obsolete. If you are still getting used to charting, and are wondering whether you are doing it correctly, and the chart is showing your ovulation with accuracy, using ovulation tests for a few cycles as a double-checking option makes a lot of sense. If the dates of your ovulation match up both on your fertility chart and your ovulation tests, you'll know that you are doing it right. Fertility charting is not right for everybody.
Personally, I don't have the patience to take my temperature every single day. I prefer using ovulation tests in combination with a simple ovulation calendar. This limits fertility hassle to only certain periods of the cycle, and makes it unnecessary for you to think about conceiving all the time.
