Hello, the first time taking birth control pills is recommended to start on the first day of your menstrual cycle.
If you begin taking the pills after the second day of your period, it is advised to use additional contraceptive measures for the first seven days of taking the pills, which may include emergency contraception methods.
Thank you! Wishing you safety and health, Dr.
Zhang.

More Info

Emergency contraception (EC) is a method used to prevent pregnancy after unprotected intercourse or contraceptive failure. It is important to clarify the distinction between pre-exposure and post-exposure scenarios when discussing emergency contraceptive options.

In your question, you mention taking pre-exposure contraception and inquire about the possibility of taking emergency contraception after having unprotected intercourse within the same month. The short answer is yes, you can take emergency contraception after having unprotected sex, even if you have been using pre-exposure contraception. However, there are several important considerations to keep in mind.

1. Types of Emergency Contraception: There are two main types of emergency contraceptive pills (ECPs): levonorgestrel (Plan B One-Step and generics) and ulipristal acetate (Ella). Levonorgestrel is most effective when taken within 72 hours (3 days) after unprotected intercourse, while ulipristal acetate can be taken up to 120 hours (5 days) after. If you are considering taking emergency contraception, it is crucial to do so as soon as possible after the unprotected intercourse for maximum effectiveness.

2. Effectiveness: The effectiveness of emergency contraception decreases the longer you wait after unprotected intercourse. If you have had unprotected sex and are within the time frame for taking ECPs, it is advisable to take them as soon as possible.
3. Health Considerations: Taking emergency contraception is generally safe for most individuals. However, it can cause side effects such as nausea, fatigue, headache, dizziness, and changes in your menstrual cycle. If you have any underlying health conditions or are taking other medications, it is wise to consult with a healthcare provider before taking emergency contraception to ensure it is appropriate for you.

4. Repeated Use: While emergency contraception is safe for occasional use, it is not intended to be a regular form of contraception. Frequent use of emergency contraception can lead to menstrual irregularities and may not be as effective as regular contraceptive methods. If you find yourself needing emergency contraception frequently, it may be beneficial to discuss long-term contraceptive options with a healthcare provider.

5. Potential for Pregnancy: If you have taken emergency contraception after unprotected intercourse, it is important to monitor for signs of pregnancy. If your period is more than a week late after taking the emergency contraceptive, consider taking a pregnancy test.

6. Consulting a Healthcare Provider: If you have any concerns about your reproductive health, the use of emergency contraception, or if you are experiencing significant side effects, it is always best to consult with a healthcare provider. They can provide personalized advice based on your health history and current situation.

In summary, you can take emergency contraception after having unprotected sex, even if you have been using pre-exposure contraception. It is important to act quickly, choose the right type of emergency contraception, and consult with a healthcare provider if you have any concerns about your health or contraceptive options.
