I have PCOS/PMOS and I am bleeding for 12 days. How to stop it?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I have been bleeding for 12 days. I have PCOS/PMOS and have been taking birth control pills for almost two years, and it started with brownish bleeding on day 13 of my active pill.

Why is this happening? I am worried.

Please help.

Hello,

Welcome to icliniq.com.

Thanks for trusting us with your health care.

I have gone through your history and understand your concern. Irregular brownish bleeding or spotting while taking active birth control pills can occur due to hormonal fluctuations and is commonly seen in women with PCOS (polycystic ovary syndrome)/PMOS (polyendocrine metabolic ovarian syndrome). This is often called breakthrough bleeding.

Such bleeding may happen because of:

  • hormonal imbalance related to PCOS/PMOS.
  • long-term use of contraceptive pills.
  • missed or delayed pills.
  • changes in the body’s response to the pill formulation.

In many cases, this settles on its own, but bleeding lasting for 12 days should be monitored carefully.

I suggest you:

  • Continue taking the pills exactly as prescribed unless your gynecologist advises otherwise.
  • Maintain a healthy diet and adequate hydration.
  • Exercise regularly and maintain a healthy weight, as lifestyle changes help in PCOS/PMOS management.

You should consult a gynecologist if:

  • The bleeding becomes very heavy.
  • You develop severe abdominal pain or dizziness.
  • You pass large clots.
  • The irregular bleeding continues for multiple cycles.

A clinical evaluation and ultrasound scan may sometimes be required to rule out other causes.

I hope this helps.

Feel free to get back in case of further doubts.

Regards.
