Is There a Chance of Pregnancy After Taking Emergency Contraceptive? - Obstetrics and Gynecology

Possible pregnancy


I took emergency contraception within 24 hours on both occasions.
After taking the morning pill, I noticed increased bleeding, but there was no bleeding in the evening.
I usually have insufficient sleep, and my period, which was expected on March 22, only showed slight bleeding from March 27 to March 29 without a full flow.
I would like to ask the doctor if there is a possibility of pregnancy, thank you.
My menstrual cycle is generally irregular, with my last period starting on February 22.

Sunny, 10~19 year old female. Ask Date: 2022/03/29

When considering the possibility of pregnancy after taking emergency contraceptive pills (ECPs), it's important to understand how these medications work and their effectiveness. Emergency contraceptive pills, such as Plan B (levonorgestrel) and Ella (ulipristal acetate), 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 for Plan B and up to 120 hours for Ella.

In your case, since you mentioned that you took the emergency contraceptive pills within 24 hours after unprotected intercourse, you significantly increased your chances of preventing pregnancy. However, no contraceptive method is 100% effective, and there is still a small chance of pregnancy even after taking ECPs.

The bleeding you experienced after taking the emergency contraceptive could be a side effect of the medication. ECPs can cause changes in your menstrual cycle, including spotting or breakthrough bleeding. This is not uncommon and can happen as your body adjusts to the hormones in the pills. The timing of your next period may also be affected; it could be earlier, later, or even lighter than usual.

Given that your menstrual cycle is irregular, it can be challenging to determine whether you are pregnant based solely on your cycle. The slight bleeding you experienced from March 27 to March 29 could be a side effect of the emergency contraceptive rather than a regular menstrual period.
To assess the possibility of pregnancy, consider the following steps:
1. Wait for Your Period: If your period does not arrive within a week of when you expect it, you should take a home pregnancy test. These tests are designed to detect the hormone hCG, which is produced during pregnancy.

2. Consult a Healthcare Provider: If you have concerns about your menstrual cycle or the effectiveness of the emergency contraceptive, it may be beneficial to consult with a healthcare provider. They can provide personalized advice and may suggest further testing if necessary.

3. Understand Your Cycle: Since you mentioned having an irregular cycle, keeping track of your menstrual patterns can help you understand your body better. Apps or calendars can assist in tracking your cycle and any symptoms you experience.

4. Consider Other Factors: Stress, changes in weight, and other health factors can also affect your menstrual cycle. If you have been experiencing significant stress or changes in your lifestyle, this may contribute to irregularities in your cycle.

In summary, while there is a small chance of pregnancy after taking emergency contraceptive pills, the likelihood is reduced significantly when taken promptly. The bleeding you experienced could be a side effect of the medication rather than an indication of pregnancy. If you are concerned about your menstrual cycle or the possibility of pregnancy, taking a home pregnancy test or consulting with a healthcare provider would be the best course of action.
