Is there a need to take emergency contraception/what is the likelihood of pregnancy?
Hello doctor, my menstrual periods in the last three months were on December 16, January 14, and February 13, with each cycle lasting one week.
The app indicates that my fertile window is from February 26 to March 3.
On March 8, I had intercourse without a condom for part of the time and then put on a condom, and ejaculation occurred inside the condom.
I would like to know if there is a need to take emergency contraception in this situation.

Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
Emergency contraception can be used as a remedy.
However, it is still recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health, Dr.
Chang.

More Info
When it comes to determining whether you need emergency contraception after unprotected intercourse, there are several factors to consider. Based on the information you provided, you had unprotected intercourse on March 8, during your fertile window, which is a crucial time for potential conception. The timing of your menstrual cycle and the nature of the intercourse are both significant in assessing your risk of pregnancy.
1. Understanding Your Cycle: Your menstrual cycle appears to be relatively regular, with periods occurring approximately every 28 days. Since your last period started on February 13, and you had intercourse on March 8, this places you within your fertile window, which typically spans from about five days before ovulation to the day of ovulation itself. If your cycle is consistent, ovulation likely occurred around February 27 to March 1, making March 8 a risky time for unprotected intercourse.
2. Unprotected Intercourse: You mentioned that you did not use a condom for the entirety of the intercourse and that ejaculation occurred inside the condom. While using a condom can significantly reduce the risk of pregnancy, it is essential to ensure that it is used correctly from the beginning to the end of intercourse. If the condom was not applied until halfway through, there is a risk that sperm may have been present before the condom was used.
3. Emergency Contraception: Emergency contraception (EC) is most effective when taken as soon as possible after unprotected intercourse. There are two main types of emergency contraception:
- Levonorgestrel (Plan B): This is effective up to 72 hours after unprotected intercourse, but its efficacy decreases the longer you wait.
- Ulipristal Acetate (Ella): This can be taken up to 120 hours after unprotected intercourse and is generally more effective than Levonorgestrel, especially closer to ovulation.
Given that your unprotected intercourse occurred on March 8, it is advisable to take emergency contraception as soon as possible if you are concerned about the risk of pregnancy. If you are within the time frame for either Levonorgestrel or Ulipristal, you should consider obtaining and taking one of these options.
4. Consulting a Healthcare Provider: It is always a good idea to consult with a healthcare provider for personalized advice. They can provide guidance based on your specific circumstances, including your menstrual cycle, any underlying health conditions, and the timing of your intercourse. They can also discuss other contraceptive options for the future to help prevent unintended pregnancies.
5. Follow-Up: After taking emergency contraception, it is essential to monitor your menstrual cycle. You may experience some irregularities in your next period, but if your period is more than a week late, consider taking a pregnancy test to confirm whether or not you are pregnant.
In summary, given the timing of your unprotected intercourse and the nature of the situation, it is advisable to take emergency contraception as soon as possible. Additionally, consulting with a healthcare provider can provide you with the best course of action tailored to your needs.
