Phase guides
The four phases of her cycle, explained for partners.
Every month her body moves through four phases, and each one asks something different of you. These guides cover what she is likely running on, what tends to help, what tends to backfire, and what to say. They are written for the partner, in plain language, and they are not medical advice.
