Taking emergency contraceptive pills can lead to a delay in menstruation?
Hello, Doctor.
I would like to ask you about my situation.
My last menstrual period started on May 28 and lasted for 3 days.
My cycles have been quite regular, around 28 to 30 days, with a light flow.
I took emergency contraception on June 5.
According to the app I use, my next period was due on June 24, but it hasn't arrived.
I bought a pregnancy test on June 26, which showed negative results.
I've been experiencing breast tenderness for several days, and as of this morning, June 28, my period still hasn't come.
How should I proceed? Thank you for your assistance.

More Info
Delayed menstruation after taking emergency contraceptive pills can be a common occurrence, and it is understandable to feel concerned about it. Emergency contraceptive pills (ECPs), such as Plan B or Ella, are designed to prevent pregnancy after unprotected intercourse, but they can also disrupt your menstrual cycle. Here’s a detailed explanation of what might be happening and what steps you can take.
Understanding the Effects of Emergency Contraceptive Pills
1. Hormonal Impact: ECPs contain hormones that can alter your menstrual cycle. They work primarily by delaying ovulation, but they can also affect the uterine lining and the timing of your period. After taking ECPs, it is not uncommon for your next period to be delayed, lighter, or heavier than usual.
2. Cycle Variability: Your menstrual cycle can naturally vary from month to month due to various factors, including stress, diet, exercise, and hormonal fluctuations. The introduction of ECPs can add to this variability, leading to changes in the timing of your period.
3. Pregnancy Testing: Since you took a pregnancy test on June 26 and it showed negative, it is a good sign that you are not pregnant. However, it is important to note that testing too early can sometimes yield false negatives. If your period does not arrive soon, consider retesting a few days later.
What to Do Next
1. Wait for Your Period: It is advisable to wait a few more days to see if your period arrives. ECPs can cause delays of up to a week or more in some cases. If your period does not come within a week of your expected date, you may want to take another pregnancy test.
2. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as breast tenderness, cramping, or any unusual discharge. These can provide further clues about what is happening with your body.
3. Consult a Healthcare Provider: If your period does not arrive within a week after your expected date, or if you have any concerning symptoms (such as severe pain or unusual bleeding), it is important to consult a healthcare provider. They can perform a more thorough evaluation and may recommend further testing or treatment if necessary.
4. Consider Stress and Lifestyle Factors: If you have been experiencing stress or significant changes in your lifestyle, these factors could also contribute to menstrual irregularities. Engaging in stress-reducing activities, maintaining a balanced diet, and ensuring adequate sleep can help regulate your cycle.
5. Future Contraceptive Planning: If you find that you are frequently relying on emergency contraception, it may be beneficial to discuss long-term contraceptive options with your healthcare provider. There are various methods available that can provide more reliable protection against unintended pregnancy.
Conclusion
In summary, a delayed period after taking emergency contraceptive pills is not uncommon and can be attributed to hormonal changes caused by the medication. It is important to monitor your symptoms, wait a little longer for your period, and consult a healthcare provider if necessary. Remember that your health and well-being are paramount, and seeking professional advice is always a good step when you have concerns about your menstrual cycle.
