Contraception & Phase

Phase is able to predict how your energy and cognition shift, by forecasting your hormone levels. Hormonal contraceptives alter your body's natural hormone patterns.
By selecting the right option, we understand how your natural hormone patterns are being altered by contraception, and can fine-tune our algorithm to better reflect your experience.

Other Approaches
Other approaches, like using a condom, tracking your cycles, or if your partner is sterilised, will not affect the hormone cycles of your own body, and therefore won't impact the predictions that Phase makes for you.
A note from Phase
A note on what Phase can and can't support.
There are some types of contraception — like the progesterone implant, the progesterone injection, or the pill (taken without a break) — where continually taking hormones puts your body into a perceived 'steady state'.
Current research suggests that with these forms of contraception, you will not experience fluctuations in energy and cognition throughout a cycle, in a way that Phase is able to predict. Phase isn't able to support you right now for these methods.
For hormonal contraception taken with breaks, Phase may not be able to consistently map meaningful changes in energy and cognition throughout your cycle. That said, the app can still help you stay connected to your cycle and aware of any patterns that do emerge.
