When it comes to starting emergency contraceptive pills (ECPs), it's important to understand their purpose and how they work in relation to your menstrual cycle. Emergency contraceptive pills, such as Plan B or Ella, are designed to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. They are most effective when taken as soon as possible after the incident, ideally within 72 hours for Plan B and up to 120 hours for Ella.

In your case, since you mentioned that your last menstrual period started on August 24 and you typically have a cycle of about 35 days, you are currently in a phase where you may be approaching ovulation, depending on your cycle's regularity. If you had unprotected intercourse after your last period and are concerned about the possibility of pregnancy, taking an emergency contraceptive pill is a valid option.

You do not need to wait for your next menstrual period to start taking ECPs. In fact, the sooner you take them after unprotected intercourse, the better the chances of preventing pregnancy. ECPs work primarily by delaying ovulation; if you have already ovulated, they may not be effective. Therefore, if you are within the time frame for taking ECPs after the incident, you should proceed with taking them without waiting for your next period.

Regarding your regular contraceptive pills (like 悅己), you can typically resume taking them after your emergency contraceptive course. However, it's advisable to consult with your healthcare provider about the best timing to restart your regular contraceptive method after taking ECPs. Generally, you can start taking your regular birth control pills again after your next menstrual cycle begins, or as directed by your healthcare provider.

It's also important to note that taking emergency contraceptive pills can sometimes cause changes in your menstrual cycle. You may experience irregular bleeding or changes in the timing of your next period. This is a common side effect and should not be a cause for alarm unless you experience severe symptoms or have concerns about pregnancy.

In summary, you can take emergency contraceptive pills anytime after unprotected intercourse, and you do not need to wait for your next menstrual cycle to start taking them. After taking ECPs, consult your healthcare provider about when to resume your regular contraceptive method. Always keep track of your menstrual cycle and any changes you experience, and don't hesitate to reach out to a healthcare professional if you have further questions or concerns.
