You use a basal thermometer and measure when she wakes up every morning, before sitting up or moving around. Record the temp each day and enter it into the app. Take LH tests near ovulation to become more accurate. With this, you can accurately track ovulation, and will only have about 10 days each month that you need to use a condom.
If she has a regular period, you will end up with 2-2.5 weeks of "safe days" and 1.5-2 weeks of "unsafe" days. Just use a condom on the "unsafe days" if you still want to poke but don't want more babies. If you are brave, you can go unprotected on the "unsafe" days and put on a condom near the end, before you finish.
