Questions related to emergency contraception?


Hello, doctor.
Three days ago (on October 14), I noticed brown discharge, so I started taking the emergency contraceptive pill (24+4 formulation, first pack) that same night.
I have taken three pills so far, but the brown discharge has decreased significantly and is now completely gone.
I would like to know why this is happening.
Can this be considered a menstrual cycle? Will this situation affect the contraceptive effectiveness? Should I continue taking the pills? Will it help regulate my cycle? Thank you!

Ms. Wu, 20~29 year old female. Ask Date: 2022/10/17

More Info


When considering the use of contraceptive pills, particularly in the context of experiencing brown discharge, it's essential to understand the physiological processes at play and how they relate to the effectiveness of the pill.

Firstly, the brown discharge you experienced could be attributed to several factors. It is not uncommon for women to notice brown spotting or discharge at various points in their menstrual cycle, especially when starting a new hormonal contraceptive. This brown discharge often consists of old blood that is being expelled from the body, which can occur at the beginning or end of a menstrual period. In your case, since you started taking the contraceptive pill shortly after noticing the discharge, it is possible that your body is responding to the hormonal changes induced by the pill.

Regarding your question about whether this can be considered a menstrual cycle, it is important to note that the contraceptive pill is designed to regulate your menstrual cycle. When you take the pill consistently, it can lead to lighter periods or even the absence of periods (amenorrhea) in some women. The brown discharge you experienced may not represent a full menstrual cycle but rather a response to the hormonal changes initiated by the pill.
As for the effectiveness of the contraceptive pill, it is generally very effective when taken correctly. The typical effectiveness rate is about 91% with typical use, and it can be as high as 99% with perfect use. Since you have started taking the pill and have been consistent with it, the contraceptive effect should not be compromised by the brown discharge. However, it is crucial to take the pill at the same time every day to maintain its effectiveness.

Continuing to take the pill is advisable unless you experience significant side effects or have specific medical concerns. The hormones in the pill will help regulate your cycle over time, and it may take a few months for your body to adjust fully. If you are concerned about the brown discharge or have any unusual symptoms, it is always best to consult with your healthcare provider for personalized advice.

In summary, the brown discharge you noticed is likely a normal response to starting the contraceptive pill and does not indicate a problem. It does not diminish the effectiveness of the pill, and you should continue taking it as prescribed. Over time, you may find that your menstrual cycle becomes more regular and predictable. If you have any further concerns or if the discharge persists or changes in nature, please reach out to your healthcare provider for further evaluation and guidance.
