Emergency contraception, also known as the morning-after pill, is a method of birth control that can be used to prevent pregnancy after unprotected sex or contraceptive failure. It is important to know the following key points about emergency contraception:

• Types: There are different types of emergency contraception, including pills containing levonorgestrel, ulipristal acetate, and the copper IUD.
• Effectiveness: The effectiveness of emergency contraception varies depending on the type used and how soon it is taken after unprotected sex. For example, the copper IUD is more effective than the pill and can be used as ongoing contraception.
• Timing: Emergency contraception is most effective when taken as soon as possible after unprotected sex, but it can still be effective up to 5 days (120 hours) after the event.
• Availability: In many countries, emergency contraception is available over the counter at pharmacies without a prescription. However, access may vary depending on local regulations and individual circumstances.
• Side Effects: Common side effects of emergency contraception may include nausea, vomiting, fatigue, and changes in menstrual bleeding patterns. It is important to consult a healthcare professional if you experience severe or prolonged side effects.
• Considerations: Emergency contraception is not intended for regular use and should not replace regular methods of contraception. It is important to discuss ongoing contraceptive options with a healthcare provider.
