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 the emergency contraceptive pill (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: 2023/01/10

More Info


Emergency contraception (EC) is a method used to prevent pregnancy after unprotected sexual intercourse or contraceptive failure, such as a broken condom. In your case, you took the emergency contraceptive pill (ECP) known as "Levonorgestrel" (often referred to by its brand name, "Plan B" or "Ella"), shortly after the incident of condom failure. Here’s what you can generally expect after taking it and how it may relate to your current situation.


What to Expect After Taking Emergency Contraception
1. Timing of Menstrual Cycle: Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but it can be taken up to 5 days after. However, its effectiveness decreases the longer you wait. Since you took it within half an hour, you maximized your chances of preventing pregnancy.

2. Menstrual Changes: After taking emergency contraception, it is common for women to experience changes in their menstrual cycle. This can include:
- Early or Delayed Period: Your period may come earlier or later than expected. Since your cycle is typically around 38 days, it might take longer for your body to adjust after taking the ECP.

- Spotting or Light Bleeding: Some women experience spotting or light bleeding after taking the pill, which can be mistaken for a period.

- Changes in Flow: Your menstrual flow may be lighter or heavier than usual.

3. Side Effects: Common side effects of emergency contraception can include:
- Nausea or vomiting
- Fatigue
- Headaches
- Breast tenderness
- Abdominal pain or cramps (which you mentioned experiencing)
4. Pregnancy Possibility: While emergency contraception is effective, it is not 100% guaranteed. If your period is more than a week late, it is advisable to take a pregnancy test to confirm whether or not you are pregnant. The chances of pregnancy are lower if you took the ECP promptly after the incident.

5. Hormonal Effects: The hormones in emergency contraception can cause temporary disruptions in your menstrual cycle. This is normal and usually resolves within one or two cycles.


Recommendations
- Monitor Your Cycle: Keep track of your menstrual cycle and any symptoms you experience. If your period does not arrive within a week of when it is due, consider taking a home pregnancy test.

- Consult a Healthcare Provider: If you have concerns about your symptoms or if you experience severe abdominal pain, heavy bleeding, or other unusual symptoms, it is important to consult a healthcare provider.

- Future Contraceptive Options: If you find yourself needing emergency contraception frequently, consider discussing long-term contraceptive options with your healthcare provider to prevent similar situations in the future.

In conclusion, your experience of mild abdominal pain after taking the emergency contraceptive is not unusual, and the absence of your period at this stage could be a result of the hormonal changes induced by the ECP. However, it is essential to remain vigilant and take a pregnancy test if your period does not arrive as expected. Always feel free to reach out to a healthcare professional for personalized advice and support regarding your reproductive health.
