Emergency Contraceptive Pills: Usage and Side Effects - Obstetrics and Gynecology

Emergency contraceptive pills (ECPs), commonly known as "morning-after pills," are designed to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. The two most common types of ECPs are levonorgestrel (Plan B One-Step) and ulipristal acetate (Ella). Both types are effective when taken as soon as possible after the incident, with levonorgestrel being most effective within 72 hours and ulipristal acetate effective up to 120 hours after unprotected sex.

In your case, you took ECPs after two separate incidents of condom failure. It’s important to note that while ECPs are effective at preventing pregnancy, they do not terminate an existing pregnancy. They work primarily by delaying ovulation, preventing fertilization, or preventing a fertilized egg from implanting in the uterus.

Regarding your concerns about side effects and the timing of your menstrual cycle, it is common for ECPs to cause some temporary changes in your menstrual cycle. After taking ECPs, some women may experience:
1. Changes in Menstrual Cycle: Your next period may come earlier or later than expected, and the flow may be lighter or heavier than usual. This is due to the hormonal changes induced by the ECPs.

2. Abdominal Pain or Cramping: It is not unusual to experience abdominal discomfort or cramping after taking ECPs. This can mimic menstrual cramps and may be a result of the hormonal changes or the body adjusting to the medication.

3. Nausea and Fatigue: Some women report feeling nauseous or fatigued after taking ECPs, although these symptoms typically resolve within a few days.

4. Breast Tenderness: Hormonal fluctuations can also lead to breast tenderness.

In your case, since you experienced abdominal pain on February 11, it could be related to the ECPs you took on February 8. However, if the pain is severe or accompanied by other concerning symptoms (such as heavy bleeding, fever, or dizziness), it is important to seek medical attention to rule out any complications.

As for the delay in your menstrual cycle, it is not uncommon for ECPs to cause a temporary disruption. If your period does not arrive within a week of when it is expected, it is advisable to take a pregnancy test to confirm whether or not you are pregnant.

In summary, while ECPs are effective for preventing pregnancy after contraceptive failure, they can cause temporary side effects and changes in your menstrual cycle. If you have any ongoing concerns or if your symptoms worsen, it is best to consult with a healthcare provider for personalized advice and to ensure your health and well-being.
