Emergency contraceptive pill


I took the emergency contraceptive pill on the morning of the 19th, and I haven't experienced any bleeding up to today.
However, from the 20th to the 23rd, I had abdominal pain and diarrhea, but on the 24th, the abdominal pain stopped, although I still have diarrhea.
Is this normal? Thank you.

It could be a side effect of the medication, but if it persists for too long, it's best to visit a clinic for a physician's evaluation.

More Info


When it comes to understanding the symptoms that may arise after taking emergency contraception (commonly referred to as the "morning-after pill"), it's essential to recognize that individual experiences can vary significantly. The symptoms you are experiencing, such as abdominal pain and diarrhea, can indeed be normal reactions to the hormonal changes induced by the emergency contraceptive pill.

Emergency contraceptive pills, like Plan B (Levonorgestrel) or Ella (Ulipristal Acetate), work primarily by delaying ovulation. However, they can also cause a range of side effects due to the sudden influx of hormones in your body. Common side effects include nausea, abdominal pain, fatigue, headache, dizziness, and changes in your menstrual cycle. In some cases, women may experience gastrointestinal symptoms, including diarrhea, which can be attributed to the hormonal changes or the body's reaction to the medication.

In your case, the abdominal pain and diarrhea you experienced from the 20th to the 23rd could be linked to the hormonal effects of the pill. It's not uncommon for women to report gastrointestinal disturbances after taking emergency contraception. The absence of bleeding after taking the pill is also not unusual; some women may not experience any withdrawal bleeding at all, while others may have their next period arrive earlier or later than expected.

It's important to monitor your symptoms. If the abdominal pain is severe or persistent, or if you experience other concerning symptoms such as heavy bleeding, fever, or severe dizziness, it would be wise to consult a healthcare professional. They can provide a thorough evaluation to rule out other potential causes of your symptoms, such as an infection or other gastrointestinal issues.

Regarding the diarrhea, if it persists beyond a few days or is accompanied by other symptoms like dehydration, it would be advisable to seek medical attention. Staying hydrated is crucial, especially if you are experiencing diarrhea.

Lastly, if you are concerned about the possibility of pregnancy despite taking the emergency contraceptive pill, consider taking a pregnancy test if your next period is delayed by more than a week. Emergency contraception is not 100% effective, and while it significantly reduces the risk of pregnancy, it does not eliminate it entirely.

In summary, the symptoms you are experiencing can be normal after taking emergency contraception, but it's essential to keep an eye on them and consult a healthcare provider if you have any concerns or if your symptoms worsen. Your health and well-being are paramount, and a healthcare professional can provide personalized advice and support.
