Pregnancy Prevention—Nearly 90%
You Should Know
- Do not swallow any extra pills. Extra pills will not further reduce your risk of pregnancy, but they could make you feel sick.
- If you throw up within one hour of taking the pills, call your doctor. You may need to repeat a dose or take anti-nausea medicine.
Call your doctor if you have any of these symptoms:
- Severe leg pain
- Severe abdominal pain
- Chest pain, cough, or shortness of breath
- Blurred or loss of vision
- Using emergency contraception frequently can cause your menstrual cycle to become irregular.
- You should start your period within a month. If you do not have a period when you expect to, take a pregnancy test.
