Breakthrough Bleeding on Birth Control Pills: What to Do Next? - Obstetrics and Gynecology

Oral contraceptives - Is there contraceptive effectiveness if bleeding occurs during use and the pills are discontinued?


Hello, Doctor.
I have been taking the oral contraceptive pill for about two years.
On August 16, I experienced unexpected bleeding, which was not like my regular period, so I continued taking the pill without interruption.
I finished all 21 pills on August 25.
However, since the bleeding was somewhat heavy and lasted a bit longer, I am wondering if I should start a new pack right away or take a seven-day break and then start on the eighth day.
I am concerned because I may have sexual intercourse in the coming days and I worry about the possibility of pregnancy.
I would appreciate your guidance.
Thank you.

Hello, sometimes birth control pills can cause changes in menstruation.
It is advisable to temporarily observe if similar situations occur next time.
Start taking the birth control pills on the fifth day of your menstrual cycle; it doesn't have to be at the exact same time, just around the same time is sufficient.
As long as you take them regularly, they will be effective for contraception.
If you forget to take a pill on a particular day, you can take the missed pill the next day.
Wishing you good health.

More Info


Breakthrough bleeding while on birth control pills can be a concerning experience, especially for those who have been using them consistently for an extended period. It's important to understand that breakthrough bleeding is relatively common among users of hormonal contraceptives, particularly during the first few months of use or when there are changes in the regimen.
When you experience unexpected bleeding while on the pill, it is crucial to assess the situation carefully. In your case, you mentioned that you have been taking the pill for about two years and experienced bleeding starting on August 16. Since you continued taking the pills without interruption and completed your pack on August 25, you are likely following the correct protocol.
Typically, the standard regimen for a 21-day birth control pill pack involves taking one pill daily for 21 days, followed by a 7-day break during which you would usually have your period. If you experience breakthrough bleeding during the active pill phase, it is generally advised to continue taking the pills as prescribed. Stopping the pills or altering the schedule can lead to further irregularities in your cycle and may increase the risk of unintended pregnancy.

Given that you are concerned about the possibility of pregnancy due to upcoming sexual activity, here are some recommendations:
1. Continue Taking the Pills: Since you have completed your current pack, you should start a new pack immediately without taking the 7-day break if you wish to maintain continuous contraception. This approach can help stabilize your hormone levels and may reduce the likelihood of further breakthrough bleeding.

2. Monitor Your Symptoms: Keep track of any additional bleeding or changes in your cycle. If the breakthrough bleeding persists or becomes heavier, it may be worth consulting your healthcare provider for further evaluation. They may suggest adjusting your pill type or dosage.

3. Consider Emergency Contraception: If you have unprotected intercourse during the time of breakthrough bleeding and are concerned about pregnancy, you may want to consider emergency contraception. This is most effective when taken as soon as possible after unprotected sex.

4. Consult Your Healthcare Provider: If you have ongoing concerns about breakthrough bleeding or if it becomes a recurring issue, it is advisable to speak with your healthcare provider. They can assess your situation, review your contraceptive method, and determine if a different type of birth control might be more suitable for you.

5. Understand the Causes: Breakthrough bleeding can occur for various reasons, including hormonal fluctuations, missed pills, or even stress. Understanding that this can happen is essential in managing your expectations and anxiety regarding your menstrual cycle.

In summary, continue taking your birth control pills as directed, consider starting a new pack immediately, and monitor your symptoms. If you have any concerns about your bleeding or potential pregnancy, do not hesitate to reach out to your healthcare provider for personalized advice and support. They can help you navigate your options and ensure that you are using the most effective method of contraception for your needs.
