It's common for women to experience fluctuations in mood and mental well-being during their menstrual cycle due to hormonal changes. To maintain your mental well-being, consider keeping a mood diary to track your feelings throughout the cycle. Engage in regular physical activity, as exercise can boost your mood and reduce stress. Practicing mindfulness or meditation can also help manage anxiety and improve emotional stability. Eating a balanced diet and staying hydrated are important too. If you find that your symptoms are severe or impact your daily life, don't hesitate to speak with your GP, who can provide support or treatment options.
