Emergency Contraception: What to Expect After Taking It - Obstetrics and Gynecology

More Info

Emergency contraception (EC) is a method used to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. The most common forms of emergency contraception are the hormonal pills, like Plan B (levonorgestrel) and Ella (ulipristal acetate), which are effective when taken within a specific timeframe after the incident. In your case, it sounds like the individual took the emergency contraceptive pills within the recommended time frame, which is a positive step toward preventing an unintended pregnancy.

After taking emergency contraception, it is common for individuals to experience some side effects, which can include nausea, fatigue, headache, dizziness, breast tenderness, and changes in menstrual bleeding patterns. The discomfort you mentioned, such as abdominal pain, is also a common side effect and usually resolves on its own.
Regarding menstrual changes, emergency contraception can affect the timing of your next period. Some individuals may experience their period earlier, while others may have a delayed period. It is not unusual for the menstrual cycle to be disrupted after taking EC, and this can lead to a period that is lighter, heavier, or different in duration than usual.
In your situation, since it has been seven days since taking the emergency contraceptive and there are no signs of menstruation, it is important to consider a few factors:
1. Timing of Ovulation: If the individual was close to ovulation when the contraceptive was taken, the effectiveness of EC may vary. If ovulation has already occurred, EC may not be effective.

2. Next Steps: If the period does not arrive within a week of the expected date, it is advisable to take a home pregnancy test. These tests are generally accurate and can provide peace of mind. If the test is positive, a follow-up appointment with a healthcare provider is recommended to discuss options.

3. Waiting Period: If the pregnancy test is negative but the period is still delayed, it is generally acceptable to wait another week or two before seeking further evaluation. Stress, hormonal fluctuations, and other factors can also contribute to a delayed period.

4. Consulting a Healthcare Provider: If there are any concerns about potential pregnancy or if the individual experiences severe side effects, it is best to consult a healthcare provider. They can provide guidance, perform a pregnancy test, and discuss further options if needed.

In summary, while it is common for emergency contraception to cause temporary changes in menstrual cycles, monitoring the situation and taking a pregnancy test if the period is significantly delayed is a prudent approach. If there are any additional concerns or symptoms, seeking medical advice is always a good idea.
