Irregular menstruation with periods coming 3-4 days earlier than expected can be caused by hormonal imbalances, stress, changes in weight or exercise, or underlying conditions like thyroid issues or polycystic ovary syndrome (PCOS).

🩺 Possible Causes

• Hormonal fluctuations affecting the menstrual cycle timing.
• Stress or lifestyle changes impacting your cycle regularity.
• Use of hormonal medications such as progestins (e.g., Medronorm) which influence menstrual patterns.

🩺 What You Should Do

• Track your menstrual cycle carefully to note any other changes or symptoms.
• Consult a gynecologist for a thorough evaluation, which may include hormone level tests or ultrasound.
• Avoid self-medicating or stopping any prescribed hormonal treatments without medical advice.

If you are currently taking or considering medications like Medronorm (medroxyprogesterone), discuss this with your doctor, as it can affect your cycle timing and cause side effects that need monitoring.

🩺 When to Seek Immediate Care
