Chloe Caldwell's period has often felt inconvenient, uncomfortable, or even painful. It's only once she's in her thirties, as she's falling in love with Tony, a musician and single dad, that its effects on her mood start to dominate her life. Spurred by the intensity and seriousness of her new relationship, it strikes her: her outbursts of anxiety and rage match her hormonal cycle. Compelled to understand the truth of what's happening to her, Chloe documents attitudes toward menstruation among her peers and family, reads Reddit threads about PMS, attends a conference called Break the Cycle, and learns about premenstrual dysphoric disorder, PMDD, which helps her name what she's been going through. For Chloe, healing isn't about finding a single cure. It means reflecting on underlying patterns in her life: her feelings about her queer identity and writing persona in the context of a heterosexual relationship; how her parents' divorce contributed to her issues with trust; and what it means to blend a family.
