11. Changes to Menstrual Cycle

Researchers estimate that more than one-fifth of women suffer depression at some time. This condition affects the hormone balance in the body, which can make women with depression more likely to experience irregular menstrual cycles. Periods might come much later than usual or be missed, and the chances of getting pregnant generally fall. Many other health conditions can also affect menstrual cycle regularity, but if a woman with irregular menstruation has four or five other symptoms of depression, there’s a chance her fertility issues are linked.
