Brown Discharge While Taking Emergency Contraceptive Pills - Obstetrics and Gynecology

Share to:

If you are experiencing brown discharge while still taking your emergency contraceptive pill, it may be a sign of breakthrough bleeding, which can occur due to hormonal fluctuations. It is advisable to monitor the situation and consult with a healthcare professional if you have any concerns or if the bleeding persists?


Hello doctor, I am taking the oral contraceptive pill "Ayi" for the first time, and I have been taking it at the regular time.
I want to ask about my current situation: I have 1.2 pills left, and I have started to notice a very small amount of brown discharge, along with a feeling of bloating in my abdomen.
Is this normal? Is the effectiveness of the pill still intact? After my period starts on the fifth day, can I buy a new pack and continue taking it? Also, how many days after stopping the pill is it normal for my period to come? Is it normal for my period to start on the first or second day after stopping the pill?

Dr. Wu Xianghui reply Obstetrics and Gynecology

More Info


When taking emergency contraceptive pills (ECPs), such as the one you mentioned (愛已), it is not uncommon to experience some side effects, including brown discharge. This brown discharge is often old blood that is being expelled from the body, and it can occur due to hormonal changes triggered by the ECPs. These pills work primarily by preventing ovulation, and they can also alter the menstrual cycle, leading to irregular bleeding or spotting.

The symptoms you described, such as a feeling of fullness or pressure in your abdomen, can also be a normal reaction to the hormonal changes induced by the ECPs. Many women report experiencing mild cramping or discomfort after taking these pills, which is generally not a cause for concern unless it becomes severe or is accompanied by other troubling symptoms.

Regarding the effectiveness of the ECPs, if you took them as directed and within the appropriate time frame after unprotected intercourse, they should still be effective. However, it’s important to remember that ECPs are not 100% effective, and their efficacy can decrease if taken later than recommended. If you experience any unusual symptoms or if your period is significantly delayed after taking the pills, it may be wise to take a pregnancy test or consult with a healthcare provider for further guidance.

As for your menstrual cycle, it is common for periods to be irregular after taking ECPs. You might find that your next period comes earlier or later than expected, and it may be lighter or heavier than usual. If you stop taking the ECPs, it is possible for your period to arrive within a few days, but this can vary widely from person to person. Some women may experience their period within 1-2 days after stopping the pills, while others may take longer.

If you are considering starting a new pack of ECPs after your next period, it is generally safe to do so. However, it is crucial to understand that ECPs are not intended for regular contraceptive use and should only be used in emergencies. For ongoing contraception, it is advisable to discuss with a healthcare provider about more reliable and regular contraceptive methods, such as birth control pills, IUDs, or other options that suit your lifestyle and health needs.

In summary, the brown discharge and abdominal discomfort you are experiencing can be normal side effects of taking emergency contraceptive pills. If you have any concerns about your symptoms or the effectiveness of the medication, it is always best to consult with a healthcare professional for personalized advice and reassurance.
