How effective is Plan B? Is it ok to take it within 5 days or 72 hours?

For the most part has Plan B successfully worked for yall?

I am a little worried i went out of town with a partner and just realized something. The first day out of town he had made the comment of he had finished in me but i took it as a joke because he has played like that.

But he wasnt smiling he seemed pretty serious . Later that night the same thing happened but i knew he had because i could feel it . When we got back to our city i took the Plan B pill at 72 hrs.

After the second time we fooled around. The reason i am now concerned is because i had forgot about the comment of he had finished in me the first time we had sexual intercourse.

I read online that you can take plan b up to 5 days after unprotected sex but it is best to take it within firs 72 hrs.

With that being said have some of you taken it withing 48/72 hrs or a little later with it succeeding?

Plan B One-Step, also known as the morning-after pill, contains levonorgestrel, a hormone used to prevent pregnancy after unprotected sex or contraceptive failure. Here's what you should know about its effectiveness and recommended usage:

Effectiveness: Plan B One-Step is most effective when taken as soon as possible after unprotected intercourse. The sooner you take it, the better it works. If taken within 72 hours (3 days) after unprotected sex, it can reduce the risk of pregnancy by 89%. However, its effectiveness decreases over time after the act.
Timing: While Plan B One-Step is recommended to be taken within 72 hours after unprotected sex, there are some studies and product labels which indicate it can be taken up to 120 hours (5 days) after. However, keep in mind it becomes less effective the longer you wait.
Factors Influencing Effectiveness: Body weight might influence the effectiveness of Plan B. Some research suggests that Plan B might be less effective or possibly ineffective in women weighing 165 pounds (75 kg) or more. This is still a subject of research, and women are advised to consult with a healthcare provider for the most suitable emergency contraception method based on their specific circumstances.
Frequency of Use: While Plan B One-Step is safe to use any time it's needed, it should not be used as a regular form of contraception because there are other methods that are more effective for regular use.
Side Effects: Some women may experience side effects like nausea, fatigue, headache, dizziness, breast tenderness, abdominal pain, and menstrual changes. If vomiting occurs within two hours of taking the pill, a woman should contact her healthcare provider as another dose may be needed.
Other Options: There are other forms of emergency contraception, like the copper IUD and a different emergency contraceptive pill called Ella (ulipristal acetate), which have different time frames and mechanisms of action.
Important Reminder: Plan B One-Step and other emergency contraceptives do not protect against sexually transmitted infections (STIs).
