Post-Pill Discharge: Is It Normal After Emergency Contraception?

Taking emergency contraceptive pills can result in increased vaginal discharge?

Hello, my previous menstrual cycles were as follows: 8/16 to 9/23 (39 days), 9/24 to 10/15 (22 days), 10/16 to 11/20 (36 days), and 11/21 to 12/08 (18 days).
It has been 35 days since 12/09, and my period has not arrived yet.
Additionally, from 1/2 to 1/5, I experienced a significant amount of discharge, with the most substantial amount on 1/4.
I had sexual intercourse on 1/8 (day 31) and 1/9 (day 32).
During the second intercourse on 1/9, I noticed that the condom slipped off, but there was no ejaculation, and I am unsure if it was without a condom.
I took Levonorgestrel 1.5 mg as an emergency contraceptive within two hours after the incident.
Since taking the medication, I have experienced a significant amount of discharge that has continued until now, which is white and watery but not thick.
Additionally, after taking the medication on 1/9, I have also experienced breast tenderness and pain.
I would like to know if it is normal for my period to be delayed at this point.
Also, was there an error in the contraceptive measures taken, and what is the likelihood of pregnancy in this situation? Thank you, doctor.

Hello, the presence or absence of pregnancy cannot be determined solely by subjective symptoms.
The failure rate of condoms as a contraceptive method is over 5%, which is less reliable compared to other methods.
Generally, it is not recommended to rely solely on condoms for contraception.
Additionally, emergency contraceptive pills are not 100% effective, with a failure rate of about 3%, but they are still considered a remedial option.
It is advised to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

More Info

After taking emergency contraception like Levonorgestrel, it is not uncommon to experience various side effects, including changes in menstrual cycles and abnormal discharge. In your case, the absence of menstruation for 35 days after taking the pill, along with the presence of significant white discharge, can be concerning but is not necessarily abnormal.

Emergency contraceptive pills (ECPs) work primarily by delaying ovulation. If taken before ovulation, they can effectively prevent pregnancy. However, if ovulation has already occurred, ECPs may not be effective. The hormonal changes induced by these medications can lead to side effects such as breast tenderness, nausea, and changes in vaginal discharge. The white, non-sticky discharge you described could be a result of hormonal fluctuations caused by the pill.

It's important to note that while ECPs are effective, they are not 100% guaranteed to prevent pregnancy. The effectiveness of Levonorgestrel is about 85% when taken within 72 hours after unprotected intercourse. Since you mentioned that you took the pill within two hours of the incident, you maximized your chances of preventing pregnancy. However, the risk is not entirely eliminated, especially if ovulation was imminent at the time of taking the pill.

The absence of menstruation can be attributed to several factors, including the hormonal effects of the emergency contraception, stress, changes in body weight, or other underlying health issues. If your period does not arrive within a week or two, it is advisable to take a pregnancy test to rule out pregnancy. If the test is negative and your period still does not come, consider consulting a healthcare provider for further evaluation.

In terms of your concern about the effectiveness of your contraceptive measures, it seems that you acted promptly by taking the emergency contraception after the potential risk. However, it's crucial to ensure that future contraceptive methods are used correctly to minimize the risk of unintended pregnancy. Regular contraceptive methods, such as birth control pills, condoms, or intrauterine devices (IUDs), can provide more reliable protection against pregnancy.

In summary, while the symptoms you are experiencing can be attributed to the hormonal changes following the use of emergency contraception, it is essential to monitor your situation closely. If your period does not arrive soon or if you have any further concerns, please seek medical advice. Your health and well-being are paramount, and a healthcare professional can provide personalized guidance based on your specific circumstances.
