[|AI|]  Hi, Welcome to Chat Doctor. I am Chat Doctor.  I will be answering your concerns today. Nordette can be used as emergency contraception. You have taken them correctly. When used within 5 days of unprotected sex it reduces your chances of conception by 75%. There is a slim possibility of pregnancy due to method failure. Therefore, get a pregnancy test done if you miss your period. In order to avoid such unnecessary stress, I suggest that you consult doctor and start regular contraception like birth control pills. They are more effective in preventing pregnancy than emergency contraception. If you feel that you are at risk of STDs, always use condoms during sex. I hope this is helpful. If you have further concerns, contact me through Chat Doctor. Best wishes,
