Emergency contraceptive pills


Hello, doctor.
I have finished the first pack of Esdian oral contraceptive pills, but my period has not arrived four days after finishing the pack.
If my period does not come after seven days, should I continue with the next pack? If my period starts on the fifth or sixth day, should I still continue taking the pills after the seven days?

Emergency contraceptive pills (ECPs), often referred to as "morning-after pills," are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. They are most effective when taken as soon as possible after the event, ideally within 72 hours, but some formulations can be effective up to 5 days later. However, it seems you are referring to a regular contraceptive pill regimen, specifically Esdian, which is a combined oral contraceptive pill.

If you have completed your first pack of Esdian and your period has not arrived by the expected time, there are a few important points to consider:
1. Understanding the Pill Cycle: The typical regimen for combined oral contraceptives like Esdian involves taking one pill daily for 21 days, followed by a 7-day break during which you usually have your period. If you have taken your pills correctly and consistently, the likelihood of pregnancy is low, even if your period is late.

2. What to Do If Your Period Is Late: If your period does not arrive within the 7-day break, it is advisable to take a pregnancy test. This is especially important if you had unprotected intercourse during the cycle or if you missed any pills. If the test is negative and you are not experiencing any other concerning symptoms, you can start your next pack of pills as scheduled.

3. Continuing the Pill: If your period does not come after the 7-day break, you should still continue with the next pack of Esdian as planned. The absence of a period does not mean you should stop taking the pills, as they are designed to regulate your menstrual cycle and prevent ovulation.

4. Possible Reasons for a Late Period: There are several reasons why your period might be late while on the pill. Stress, changes in weight, illness, and hormonal fluctuations can all affect your cycle. Additionally, some women may experience lighter periods or skipped periods while on hormonal contraceptives, which is generally considered normal.

5. Consulting a Healthcare Provider: If you are concerned about your late period or if you experience unusual symptoms (such as severe abdominal pain, unusual discharge, or symptoms of pregnancy), it is important to consult with your healthcare provider. They can provide personalized advice and may suggest further evaluation if necessary.

6. Importance of Consistency: To maintain the effectiveness of your contraceptive method, it is crucial to take your pills consistently at the same time every day. Missing pills or taking them irregularly can increase the risk of unintended pregnancy and can also affect your menstrual cycle.

In summary, if your period is late after completing your first pack of Esdian, take a pregnancy test to rule out pregnancy. If negative, continue with your next pack as scheduled. If you have any concerns or experience unusual symptoms, reach out to your healthcare provider for guidance. Regular communication with your healthcare provider is essential for managing your reproductive health effectively.
