Emergency contraceptive pills (ECPs), such as the one you mentioned (Jellytin), are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. They are most effective when taken as soon as possible after the incident, ideally within 72 hours, but some types can be effective up to 120 hours (5 days) after intercourse. However, their effectiveness can be influenced by several factors, including the timing of administration relative to intercourse, the timing within the menstrual cycle, and the frequency of intercourse.

In your case, you mentioned having unprotected intercourse on May 22 and taking the emergency contraceptive pill afterward. If you had subsequent unprotected intercourse shortly after taking the ECP, it is important to note that the ECP will not be effective against any intercourse that occurs after it has been taken. Therefore, if you had unprotected intercourse again after taking the ECP, you would need to take another dose of the emergency contraceptive pill to prevent pregnancy from that subsequent act.

Regarding your question about the likelihood of pregnancy during the "safe period," it is essential to understand that the concept of a "safe period" is based on the menstrual cycle and ovulation. The fertile window typically occurs around the time of ovulation, which is usually about 14 days before the start of your next period. If you had intercourse during this fertile window, the chances of pregnancy increase significantly, regardless of whether you took an ECP.

In summary, if you had unprotected intercourse after taking the emergency contraceptive pill, the effectiveness of that pill would not extend to the later acts of intercourse. If you are concerned about the possibility of pregnancy, it is advisable to take another dose of emergency contraception as soon as possible after the subsequent unprotected intercourse. Additionally, if you are unsure about your risk of pregnancy or have further questions, consulting with a healthcare provider is always a good idea. They can provide personalized advice based on your specific situation and help you understand your options moving forward.

Lastly, while emergency contraceptive pills are a useful option for preventing unintended pregnancies, they are not intended for regular use as a primary contraceptive method. For ongoing contraception, consider discussing more reliable methods with your healthcare provider, such as hormonal birth control, IUDs, or other long-term options that may suit your lifestyle and health needs better.
