Emergency contraceptive pill


Hello doctor, my last menstrual period was from December 2 to December 7, with a cycle of about 38 days.
I had protected sexual intercourse on December 30, January 4, and January 7.
On January 7, my boyfriend's condom was inside out and it broke.
I took emergency contraception (Levonorgestrel) within half an hour after intercourse.
After taking it, I only experienced slight abdominal pain the next morning.
My period has not arrived yet, and I have very little discharge.
I would like to know if this is normal and if there is a possibility of pregnancy.

Hung, 10~19 year old female. Ask Date: 2023/01/09

Hello, you should not be pregnant.
Wait another week, and if your period still hasn't arrived, I recommend seeing a gynecologist.
Wishing you good health.

More Info


Emergency contraceptive pills (ECPs), such as the one you mentioned (likely referring to Levonorgestrel or Ulipristal Acetate), are designed to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. It’s important to understand how these pills work, what side effects you might experience, and what to expect in terms of your menstrual cycle following their use.


What to Expect After Taking Emergency Contraceptive Pills
1. Timing of Menstrual Cycle: ECPs can affect your menstrual cycle. After taking the pill, your next period may come earlier or later than expected. Given that your cycle is approximately 38 days, it’s possible that your period may not arrive until later than usual. If your period is delayed by more than a week from when you expect it, you should consider taking a pregnancy test.

2. Common Side Effects: It’s not uncommon to experience some side effects after taking ECPs. These can include:
- Nausea or vomiting
- Fatigue
- Headaches
- Breast tenderness
- Changes in your menstrual bleeding (heavier or lighter than usual)
- Spotting or breakthrough bleeding
The mild abdominal pain you experienced the day after taking the pill could be a normal side effect, as your body adjusts to the hormonal changes induced by the ECP.

3. Effectiveness: ECPs are most effective when taken as soon as possible after unprotected intercourse. Since you took the pill within 30 minutes of the condom breaking, you maximized your chances of preventing pregnancy. However, no contraceptive method is 100% effective, and there is still a small chance of pregnancy.

4. Pregnancy Testing: If your period does not arrive within a week of when you expect it, it is advisable to take a home pregnancy test. These tests are generally accurate and can provide peace of mind. If the test is positive, you should consult a healthcare provider for further guidance.

5. Follow-Up: If you continue to have concerns about your menstrual cycle or potential pregnancy, or if you experience severe side effects, it’s important to follow up with a healthcare provider. They can provide personalized advice and support based on your specific situation.


Conclusion
In summary, it is normal for your menstrual cycle to be affected after taking emergency contraceptive pills. The mild abdominal discomfort you experienced is also a common side effect. Keep an eye on your cycle, and if your period is significantly delayed, consider taking a pregnancy test. If you have any further questions or concerns, do not hesitate to reach out to a healthcare professional for assistance. Remember, understanding your body and its responses to medications is crucial in managing your reproductive health effectively.
