Not Fertile

Check your fertility status

On red days, you are very likely to be fertile and need to use protection or abstain to prevent a pregnancy.

On green days, you are not fertile and don’t need to use protection to prevent a pregnancy.

Remember: predictions are a forecast of the coming days. You will have an idea of your fertility status, but it may change as the algorithm updates.
