Mei Shih Nong oral contraceptive pills for regulating menstruation?


Hello doctor, I have symptoms of polycystic ovary syndrome that cause irregular menstrual periods.
I started taking Metformin on September 25 to regulate my cycle.
I would like to ask if I can take it for one month and then stop to see if I can menstruate without medication, as I am concerned about becoming dependent on the medication.
The doctor mentioned that if I don't take the medication and my period doesn't come for two months, I need to return to the hospital.
Can I stop the medication for a while to observe, and if my period does not come, can I continue taking the originally prescribed medication? Thank you.

Managing irregular periods, especially in the context of polycystic ovary syndrome (PCOS), can be a complex issue that requires careful consideration of both medical advice and personal health goals. When it comes to birth control pills, particularly those like Metformin that are often prescribed to help regulate menstrual cycles in women with PCOS, it’s essential to understand how these medications work and the implications of pausing them.

First, it’s important to recognize that birth control pills are often used to manage irregular periods by providing a consistent hormonal level that can help regulate the menstrual cycle. For women with PCOS, irregular periods are common due to hormonal imbalances, and medications like birth control pills can help restore a more regular cycle. However, it’s understandable to be concerned about becoming reliant on medication for menstrual regulation.

In your case, since you have been taking the pills since September 25 and are considering pausing them after three months, it’s crucial to approach this decision with caution. Here are some key points to consider:
1. Consult Your Healthcare Provider: Before making any changes to your medication regimen, it’s vital to discuss your concerns with your healthcare provider. They can provide personalized advice based on your medical history, the severity of your symptoms, and your overall health goals. Your doctor may suggest a specific plan for tapering off the medication or may recommend continuing it for a longer period to achieve better regulation.

2. Understanding the Risks of Stopping: If you decide to pause your birth control pills, be aware that your menstrual cycle may revert to its irregular state. This could mean that you might not have a period for an extended period, which could lead to further complications associated with PCOS, such as increased risk of endometrial hyperplasia (thickening of the uterine lining) due to prolonged absence of menstruation.

3. Monitoring Your Cycle: If you do choose to stop the medication, keep a close eye on your menstrual cycle. Document any changes, including the timing of your periods and any symptoms you experience. This information will be valuable for your healthcare provider if you need to return to the clinic for further evaluation.

4. Potential for Resuming Medication: If you stop taking the pills and do not have a period within a reasonable timeframe (as your doctor mentioned, two months), it is advisable to return to your healthcare provider. They may recommend resuming the medication or exploring other treatment options to manage your symptoms effectively.

5. Lifestyle Considerations: In addition to medication, lifestyle changes can significantly impact the management of PCOS and irregular periods. Regular exercise, a balanced diet, and maintaining a healthy weight can help improve insulin sensitivity and hormonal balance, potentially leading to more regular menstrual cycles.

6. Long-term Management: PCOS is a chronic condition that often requires ongoing management. While it’s understandable to want to reduce reliance on medication, it’s essential to have a long-term plan in place. This may include regular check-ups with your healthcare provider, monitoring your symptoms, and making lifestyle adjustments as needed.

In summary, while it is possible to pause your birth control pills, it is essential to do so under the guidance of your healthcare provider. They can help you weigh the benefits and risks and develop a plan that aligns with your health goals. Remember that managing PCOS and irregular periods often requires a multifaceted approach, including medication, lifestyle changes, and regular monitoring.
