Emergency contraceptive pills (ECPs) effectiveness


I'm sorry to bother you again, doctor.
After taking the emergency contraceptive pill on June 29, I felt something unusual in my abdomen the next day.
Today, my abdomen feels a bit tight, and sometimes I experience slight pain.
I'm not sure if this is normal or if it could be a sign of pregnancy.
I'm really worried, so I'm asking again.
When I see the doctor on July 6, what can be determined?

Dongdong, 20~29 year old female. Ask Date: 2020/07/01

Hello, this is not a sign of pregnancy; you can observe it for now.
Wishing you good health.

More Info


The use of emergency contraceptive pills (ECPs), such as Plan B or Ella, is a common method to prevent pregnancy after unprotected intercourse or contraceptive failure. These pills work primarily by delaying ovulation, preventing fertilization, or inhibiting implantation of a fertilized egg. However, they can also lead to various side effects, which may cause concern for users.

After taking an emergency contraceptive pill, it is not uncommon to experience some side effects. These can include nausea, fatigue, headache, dizziness, breast tenderness, and changes in your menstrual cycle. Some women report abdominal discomfort, which can manifest as cramping or a feeling of tightness in the abdomen. This discomfort is generally considered a normal response to the hormonal changes induced by the pill.

In your case, experiencing a "tight" feeling in your abdomen and slight pain after taking the ECP could be attributed to the hormonal fluctuations caused by the medication. It is important to note that these symptoms do not necessarily indicate pregnancy. However, if you are concerned about the possibility of being pregnant, it is advisable to take a pregnancy test if your next period is delayed by more than a week.

Regarding your upcoming doctor's appointment on July 6, your healthcare provider may perform a pregnancy test if you express concerns about potential pregnancy. They can also assess your symptoms and provide guidance on what to expect in terms of your menstrual cycle following the use of ECPs. It is important to communicate all your symptoms and concerns during this visit, as this will help your doctor provide the best care possible.

In terms of what to expect after taking an emergency contraceptive pill, it is common for your next menstrual period to be affected. Some women may experience their period earlier or later than expected, and the flow may be lighter or heavier than usual. If your period is more than a week late, it is recommended to take a pregnancy test for reassurance.

If you experience severe abdominal pain, heavy bleeding, or any other concerning symptoms, it is crucial to seek medical attention promptly, as these could be signs of complications that require immediate care.

In summary, while experiencing abdominal discomfort after taking an emergency contraceptive pill can be concerning, it is often a normal side effect of the medication. Your upcoming doctor's appointment will be an excellent opportunity to discuss your symptoms, take a pregnancy test if necessary, and receive personalized advice based on your health history and current situation. Remember, it is always better to seek medical advice when in doubt about your health.
