The common side effects of i-Pill are usually mild and short-lived : nausea, vomiting, headache, dizziness, breast tenderness, stomach cramps, fatigue, spotting, and changes in your next period such as it coming earlier, later, heavier, or lighter than usual. These effects are commonly reported after emergency contraception with levonorgestrel, and most settle on their own.

What to expect

  • Period changes: delayed, early, heavier, lighter, or irregular bleeding.
  • Stomach-related symptoms: nausea, vomiting, and abdominal cramps.
  • Other common effects: headache, dizziness, tiredness, breast tenderness, and mood swings.

When to get help

Seek medical care if you have very heavy bleeding, severe lower abdominal pain, fainting, signs of allergy, or if your period is more than a week late , because that can need evaluation.
