The goal of this observational study is to learn about the relationship between changes in ovarian hormones (estrogen and progesterone) and adolescent depression. The main question it aims to answer is:
Can we identify a subset adolescents assigned female at birth with a history of depression who are particularly sensitive to changes in ovarian hormones? Participants will be monitoring daily absolute ovarian hormone levels at home using the Mira Analyzer and answer online survey questions about their mental health for 90 days.
