Why do I get irregular periods while breastfeeding during perimenopause?

Experiencing irregular periods while breastfeeding during perimenopause is common, and the timing is not random. Your body's hormonal fluctuations interact with your environment, activity level, and stress response to trigger symptoms at specific moments.

While breastfeeding, your body may be more susceptible to irregular periods because of factors like temperature changes, physical exertion, stress hormones, or blood sugar fluctuations. Estrogen helps regulate many of these systems, and when levels are unpredictable, your body's response becomes less predictable too.

Practical strategies: Pay attention to what happens in the 30 minutes before irregular periods starts while breastfeeding. Common triggers include caffeine, alcohol, spicy foods, warm environments, sudden stress, and blood sugar drops. Once you identify your personal triggers, you can plan around them.

Logging when irregular periods occurs while breastfeeding helps you build a clear picture of your patterns and share useful data with your healthcare provider.
