COVID-19 vaccine. Dr. Hannah Feiner, a doctor at the Women’s College Hospital Bay Centre for Birth Control in Toronto, has heard these stories too, in her practice. “It’s come up in conversation—maybe their menstrual period is heavier this month, or maybe it’s lighter, or maybe it’s lasted longer or it was shorter,” she says.
