Hi, Last month we had a contraceptive failure and after consulting a local gynecologist my wife took an unwanted 72 within 30 hours. After taking the medicine she suffered from nausea and dizziness for a week. Her period was due on 27th december and she had her periods on 27th. Though the discharge was dark colored and foul smelling. After that she was doing well, now a week ago she has started having dizziness throughout the day and her body temperature is quite high in the morning. Does this mean the medicine did not work? Her period is due on 25th january. Kindly advice.
