What you need is not medical consultation but rather a refresher on sexual health knowledge.
For such inquiries, it is recommended to refer to the National Health Administration's "Sexual Well-being e-Learning" or the Obstetrics and Gynecology Society's "Consultation Guide for Adolescent Contraception" at http://goo.gl/dc6PfW.

More Info

When considering the possibility of pregnancy after unprotected intercourse, it is essential to understand the timing of ovulation, the lifespan of sperm, and the effectiveness of emergency contraception. Based on your timeline, you mentioned taking emergency contraception (悦己) on October 20 and having unprotected intercourse with ejaculation on November 5.
To assess your risk of pregnancy, let’s break down the factors involved:
1. Timing of Ovulation: The average menstrual cycle lasts about 28 days, but it can vary from person to person. Ovulation typically occurs around 14 days before the start of your next period. If your cycle is regular, tracking your ovulation can help you understand your fertile window. If you had intercourse on November 5, it is crucial to know when your next period is expected. If your cycle is around 28 days, your next period would be expected around November 21.
2. Sperm Lifespan: Sperm can live inside the female reproductive tract for up to five days. If you had unprotected intercourse during your fertile window (which is usually a few days before and the day of ovulation), there is a higher risk of pregnancy. However, if your ovulation occurred before November 5, the risk of pregnancy decreases significantly.

3. Emergency Contraception: You mentioned taking emergency contraception on October 20. This medication is most effective when taken as soon as possible after unprotected intercourse. It can reduce the risk of pregnancy by preventing ovulation or fertilization. If you took it before your fertile window, it would have significantly lowered your chances of becoming pregnant.

4. Symptoms and Signs: If you are experiencing symptoms that are commonly associated with early pregnancy, such as breast tenderness, nausea, or fatigue, it is essential to consider that these symptoms can also be related to hormonal changes in your menstrual cycle or side effects from the emergency contraception.
5. Next Steps: If your period is delayed by more than a week from when you expect it, it would be advisable to take a home pregnancy test for confirmation. These tests are generally reliable and can provide you with a clear answer. If you have any doubts or if the test is positive, consulting with a healthcare provider is recommended for further evaluation and guidance.

In summary, while there is a possibility of pregnancy after unprotected intercourse, the use of emergency contraception and the timing of your cycle play significant roles in determining your risk. If you are concerned about pregnancy, monitoring your cycle and taking a pregnancy test if your period is late will provide clarity. Remember, it is always best to consult with a healthcare professional for personalized advice and support regarding your reproductive health.
