When it comes to emergency contraception (EC) after unprotected sex, it's important to understand how it works and the timing involved. Emergency contraception is designed to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. The most common forms of EC are the morning-after pill, which can be taken in two main types: levonorgestrel (Plan B) and ulipristal acetate (Ella).
In your case, since you had unprotected sex on the night of April 3rd and took emergency contraception on April 4th, you have already taken a step to prevent pregnancy from that encounter. However, since you had another instance of unprotected sex on April 4th in the afternoon, it is advisable to take emergency contraception again. The effectiveness of the morning-after pill diminishes the longer you wait after unprotected intercourse, so taking it as soon as possible is crucial.

Levonorgestrel is most effective when taken within 72 hours (3 days) after unprotected sex, while ulipristal acetate can be effective up to 120 hours (5 days) after. If you are considering taking the morning-after pill again, it is important to choose the right one based on how much time has passed since the second unprotected encounter.
Additionally, if you are unsure about the timing or the effectiveness of the emergency contraception you have taken, consulting with a healthcare provider is a good idea. They can provide personalized advice based on your specific situation and help you understand your options moving forward.

It's also worth noting that emergency contraception does not protect against sexually transmitted infections (STIs). If you have concerns about STIs, especially given the nature of your sexual encounters, it may be wise to get tested. Regular STI screenings are recommended for sexually active individuals, particularly if you have multiple partners or engage in unprotected sex.

In summary, since you had unprotected sex again after taking emergency contraception, you should take another dose of EC as soon as possible. Consult with a healthcare provider for the best course of action and to discuss any concerns regarding STIs or other reproductive health issues. Remember, while emergency contraception is a useful tool, it should not be relied upon as a regular method of birth control. Regular contraceptive methods, such as condoms or hormonal birth control, are more effective for ongoing prevention of unintended pregnancies and STIs.
