I'm sorry to hear that you're experiencing heavy bleeding and weakness during your menstruation.

Excessive menstrual bleeding lasting more than a week, known as menorrhagia, can lead to symptoms like weakness due to blood loss. This condition may be caused by hormonal imbalances, uterine fibroids, or other underlying health issues.

Here are some important points to consider:

• Medical Evaluation: It is essential to consult a gynecologist to determine the cause of your heavy bleeding and weakness. They may recommend blood tests, ultrasound, or other investigations.
• Treatment Options: Depending on the diagnosis, treatments may include hormonal therapy, such as progesterone supplements (like the medication mentioned, which helps regulate menstrual cycles), iron supplements to address anemia, or other specific interventions.
• Lifestyle and Self-care: Maintaining a balanced diet rich in iron (e.g., leafy greens, red meat) and staying hydrated can help manage weakness. Avoiding excessive physical strain during heavy bleeding is also advisable.
• When to Seek Immediate Help: If you experience very heavy bleeding soaking through pads every hour, severe weakness, dizziness, or fainting, seek emergency medical care promptly.
