Ovulation is the release of an egg from the ovary. It occurs about 14 days before the start of your period. Checking your temperature can help you determine when you are ovulating. This information can be helpful if you are trying to conceive or avoid pregnancy.
To check your temperature for ovulation, you will need a basal body thermometer. This type of thermometer is more sensitive than a regular thermometer and can detect small changes in your body temperature. You will also need to keep a record of your temperatures on a chart.
