Seeing your Oura temperature trends in Clue can help you learn more about your cycle, all in one place. Changes in Oura temperature trends are related to changes in your basal body temperature (BBT). Since reproductive hormones have an affect on temperature, you can use this information to know where in your cycle you are.
For example, BBT is slightly lower in the follicular phase (the first half of the menstrual cycle), and rises after ovulation and stays high throughout the luteal phase (the second half of the menstrual cycle). Since Oura temperature trends change similarly to BBT across your cycle, you can use this information to know in which phase of your cycle you are and if and when you have ovulated. Please remember that it is not safe to use this feature as a form of contraception.
