When you’re trying to conceive, charting your basal body temperature is one of the easiest – not to mention free way – to predict ovulation. If you haven’t charted your BBT before, start with the day you get your period. So Day 1 on your chart would be Day 1 of your Period.

Each day, take your temperature with the Digital Basal Thermometer. Put a dot on the chart that matches your temperature. Connect the dots to see how your BBT fluctuates on a daily basis. Right around the time you ovulate, you will notice a spike in temperature. Sometimes, it takes a few months (a couple of cycles) before you can see a pattern of when you ovulate. This can help you predict when the best time to have sex is. Good luck!
Helpful Tip: Take your temperature at the same time every day. This will make your charting the most accurate. Many women record their basal body temperature when they first wake up everyday. If you need to, set an alarm for the time you record your BBT.
