Is it possible to be pregnant?


Hello, doctor.
I would like to ask about contraception issues.
I took the emergency contraceptive pill on the morning of December 24th, and my menstrual period started on December 26th, lasting until December 30th.
There was a brief moment of unprotected intercourse on the fifth day, but I pulled out immediately.
Is there a possibility of becoming pregnant?

Huang, 20~29 year old female. Ask Date: 2024/01/16

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
Additionally, the effectiveness of emergency contraception is not 100%, with a failure rate of about 3%.
However, it is still considered a remedial method.
If you are uncertain whether December 26th is the start of your menstrual period, it is advisable to check for pregnancy.
Thank you! Wishing you peace and health.
Dr.
Chang

More Info


When it comes to emergency contraception, it’s important to understand how it works and its effectiveness. 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 incident, ideally within 72 hours, but some types can be taken up to 5 days later.

In your case, you mentioned taking emergency contraception on December 24 and then having your menstrual period start on December 26. This is a crucial detail because the onset of your period is a strong indicator that you are not pregnant. The emergency contraceptive works primarily by delaying ovulation; if you have already ovulated, it may not be effective. However, since you got your period shortly after taking the ECP, it suggests that ovulation was likely delayed, and the contraceptive worked as intended.

Regarding the incident on December 30, where there was brief unprotected intercourse, the risk of pregnancy is low, especially since you had already had your period. Sperm can live inside the female reproductive tract for up to five days, but given that you had your menstrual cycle, it is unlikely that you were still in a fertile window at that time.

To summarize, the chances of getting pregnant after taking emergency contraception, followed by the onset of your menstrual period, and then a brief episode of unprotected intercourse, are very low. However, if you have concerns about potential pregnancy or if your next period is late, it would be wise to take a pregnancy test or consult with a healthcare provider for further evaluation.

In terms of your overall reproductive health, if you find yourself frequently relying on emergency contraception, it may be beneficial to discuss more reliable, long-term contraceptive options with a healthcare professional. There are many effective methods available, including hormonal birth control pills, intrauterine devices (IUDs), and implants, which can provide more consistent protection against unintended pregnancy.

Lastly, if you have any further questions or concerns about your reproductive health, menstrual cycle, or contraceptive methods, don't hesitate to reach out to a healthcare provider. They can provide personalized advice based on your medical history and lifestyle.
