What you need is not medical consultation but rather a remedial course in sexual education.
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 "Adolescent Contraceptive Guidance Consultation" at http://goo.gl/dc6PfW.

Hello, the irregularity in your cycle recently makes it difficult to predict your ovulation period and the timing of your menstruation.
Additionally, pregnancy cannot be determined based solely on subjective symptoms.
It is advisable to consult your physician for ultrasound and other relevant diagnostic tests.
Thank you! Wishing you safety and health, Dr.
Chang.

When it comes to unprotected intercourse during menstruation, the question of whether to take emergency contraception (EC) can be complex and depends on several factors. First, it’s important to understand the timing of ovulation in relation to your menstrual cycle, as this significantly influences the likelihood of pregnancy.

Typically, a woman’s menstrual cycle lasts about 28 days, but it can vary from 21 to 35 days. Ovulation usually occurs around the midpoint of the cycle, approximately 14 days before the start of the next period. Sperm can live inside the female reproductive tract for up to five days, which means that if you have unprotected intercourse just before or during ovulation, there is a higher chance of sperm meeting an egg.

In your case, you mentioned having unprotected intercourse during your menstrual period (February 5-8) and again shortly after your period ended (February 17-19). If your cycle is regular and you ovulate around day 14, the risk of pregnancy from intercourse during your period is generally lower, as ovulation typically occurs later in the cycle. However, cycles can vary, and some women may ovulate earlier or later than expected.

You also mentioned experiencing abdominal pain on February 24, which could be related to various factors, including ovulation pain, menstrual cramps, or even early signs of pregnancy. If you are concerned about the possibility of pregnancy, taking emergency contraception is an option. EC is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but some types can be effective up to 5 days after.

Here are some considerations regarding the use of emergency contraception:
1. Timing: If you had unprotected intercourse after your period and are within the window for taking EC, it is advisable to take it as soon as possible. The sooner you take it, the more effective it will be.

2. Menstrual Cycle Awareness: Understanding your cycle can help you assess your risk. If you have a regular cycle and know when you typically ovulate, you can better gauge the likelihood of pregnancy from unprotected intercourse.

3. Symptoms: If you experience unusual abdominal pain, it’s important to monitor your symptoms. If the pain persists or worsens, or if you experience other symptoms such as missed periods, nausea, or breast tenderness, consider taking a pregnancy test or consulting a healthcare provider.

4. Consultation: If you are unsure about your risk of pregnancy or the appropriateness of taking EC, it’s always a good idea to consult with a healthcare professional. They can provide personalized advice based on your health history and current situation.

5. Future Prevention: If you find yourself in a situation where you are frequently concerned about unprotected intercourse, consider discussing long-term contraceptive options with your healthcare provider. There are various methods available, including hormonal birth control, IUDs, and barrier methods, which can help prevent unintended pregnancies.

In summary, while the risk of pregnancy from unprotected intercourse during menstruation is generally lower, it is not zero. If you are concerned about the possibility of pregnancy, taking emergency contraception is a prudent step, especially if you are within the appropriate time frame. Always keep track of your menstrual cycle and consult with a healthcare provider for personalized advice and options for ongoing contraception.
