Emergency contraceptive pill


Hello, Doctor: A few days ago, I had unprotected sexual intercourse with my girlfriend during her fertile period.
As a result, I took Ella, an emergency contraceptive pill.
However, after taking it, I started experiencing abdominal pain.
Today is the fifth day since taking the pill.
On the night I took the medication, I had severe pain, which gradually decreased each day, reaching its lowest point on the third day.
However, on the fourth day, the pain returned, and today I am experiencing intense pain (even worse than on the first day).
My expected menstrual period is around December 15 (under normal circumstances).
The pain during the first to third days was on the left and right sides of my lower abdomen, while the pain on the fourth and fifth days is in the middle and sides of my lower abdomen, resembling menstrual cramps.
I have never experienced this sensation before my period.
Doctor, could you please explain what might be causing this severe pain? Is it due to the contraceptive pill, anxiety, or a sign of impending menstruation? If the severe pain continues, can I take pain relievers? Will taking pain relievers affect the efficacy of the contraceptive pill or have any adverse effects on my body? Thank you for your patient response.

Hello Mr.
66555: (I apologize for the delayed response due to personal illness.) After taking emergency contraception, if there is severe abdominal pain, it is advisable to seek medical attention.
This is important to rule out other causes of abdominal pain or to determine if it is a side effect of the medication.
After taking emergency contraception, it is possible for the menstrual cycle to be temporarily affected, which may include uterine bleeding or an early onset of menstruation.
If your girlfriend is experiencing severe abdominal pain five days after taking the emergency contraception, it could be related to these conditions.
If you are concerned, it is best to have a doctor evaluate her at the hospital.
For severe pain, you may consider using pain relievers temporarily.
However, if the pain does not subside, it is still necessary to go to the hospital.
(Pain relievers generally do not affect the efficacy of the contraceptive.)

More Info


After taking Ella, a common emergency contraceptive pill, it's not unusual to experience some side effects, including abdominal pain. The pain you're describing can be attributed to several factors related to the hormonal changes induced by the medication, as well as the natural physiological processes occurring in your body.

Ella contains ulipristal acetate, which works primarily by delaying or inhibiting ovulation. This hormonal intervention can lead to various side effects, including nausea, headache, fatigue, and abdominal pain. The abdominal pain you are experiencing could be a result of the medication's effects on your hormonal balance, which may cause your body to react similarly to how it would during a menstrual cycle. This is particularly relevant since you mentioned that your expected period is around December 15, and your body may be preparing for menstruation, which can also cause cramping and discomfort.

The pattern of your pain—intense initially, then decreasing, and then increasing again—could suggest that your body is responding to the hormonal changes and possibly preparing for menstruation. It's also possible that anxiety or stress about the situation could exacerbate your perception of pain. Stress can lead to muscle tension and increased sensitivity to pain, which might explain the fluctuations in your discomfort.

Regarding the use of pain relief medications like ibuprofen or other over-the-counter pain relievers, it is generally safe to take them while on Ella. There is no significant evidence to suggest that common pain relievers will interfere with the effectiveness of emergency contraceptive pills. However, it is always wise to consult with a healthcare provider before combining medications, especially if you have any underlying health conditions or are taking other medications.

If your pain persists or worsens, or if you experience additional symptoms such as heavy bleeding, fever, or severe discomfort, it is crucial to seek medical attention. These could be signs of other conditions that may require treatment, such as an ectopic pregnancy or other gynecological issues.

In summary, while abdominal pain after taking Ella can be concerning, it is often a normal side effect of hormonal changes. Pain relief medications can typically be used without affecting the efficacy of the contraceptive. However, monitoring your symptoms and consulting with a healthcare professional if they worsen is essential for your health and peace of mind.
