Morning-after pills are a type of emergency contraception that can help prevent pregnancy if taken within a few days after unprotected sex. The most common side effects of morning-after pills include:

• Nausea or vomiting
• Dizziness
• Fatigue
• Headache
• Breast tenderness
• Bleeding between periods or heavier menstrual bleeding
• Lower abdominal pain or cramps

These side effects typically last only a few days and are mild for most people. However, taking extra birth control pills can cause more serious side effects in some people, such as an increased risk of blood clots. If you throw up within 2 hours of taking the pill, it wont work and you’ll need to take it again. Emergency contraception should be started as soon as possible after unprotected intercourse, and within 120 hours for maximum effectiveness. If you have any concerns or experience severe symptoms after taking the morning-after pill, its recommended to reach out to your healthcare provider.
