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. Therefore, to keep Phase as accurate as possible, we ask about your contraception type during onboarding and in your settings.
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.
Not sure which type of contraception you’re using? Check out the guide below for more details on common contraceptive methods.
If you’re still stuck, feel free to reach out to us at support@phaseapp.io, for further information.
If you take a pill:
Combined pill (COCP) - daily pill with estrogen & progesterone
Progesterone only pill - daily pill containing only progesterone
If you have a coil:
Copper coil (IUD) - Hormone-free coil placed in the uterus
Progesterone Coil (IUS) - Hormonal coil placed in the uterus
If you have an implant:
Progesterone implant - small rod inserted under the skin
If you use a Vaginal Ring:
Vaginal Ring - flexible ring inserted into vagina
If you have an injection:
Progesterone injection - hormone shot every 8-13 weeks
If you have a Contraceptive Patch:
Contraceptive Patch - an adhesive patch worn on the skin
If you use 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 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. As such, we’re afraid to say that Phase isn’t able to support you right now.
If you are using hormonal contraception with a break, then the contraceptive will keep your hormone levels mostly stable, with some fluctuations during your break or placebo week. 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.
