I have gone through your query. I want to make it clear that ovulation takes place on 14th day of 28 days cycle and on 12th day of 26 days cycle. Start of period is considered first day of cycle. You have mention that you were ovulating at the time of intercourse, there is highest chance of being pregnant.Nordette
is a regular oral contraceptive
pill and cannot be effective for emergency contraception
. I will advise you to visit local OBS/GYN for any other methods available in your country.
Do consider a positive feedback as a credit to my work. Let me know if you have any further questions.
