Bleeding about one week after taking the morning-after pill is a common side effect and is usually not a cause for concern. It often happens as light spotting or an early, irregular period.
This occurs because the pill temporarily changes hormone levels, which can affect the timing and pattern of your menstrual cycle. Some people experience unexpected bleeding within the first week, while others notice their next period comes earlier or later than usual.
Cycle changes can vary depending on when the pill was taken during your cycle. In many cases, these changes are short-term and your cycle returns to normal by the next period. However, if your period is more than a week late, or if bleeding is heavy or ongoing, it may need further evaluation.
If you have severe lower abdominal pain, very heavy bleeding, or think you might be pregnant, seek medical care promptly. A gynecologist can help assess symptoms and rule out complications. Avoid taking additional medications without guidance.
