Hi, You had dropped your Nuvaring for two days (this can stimulate ovulation within few days of drop) and had an unprotected sex during the gap only. Then you took emergency contraceptive 5 days after the sex which is not likely to alter the possible conception. But it would cause disturbance in your hormonal pattern and so delay your period. You started with Nuvaring again and stopped it a week earlier, in hope of having bleeding. It s not likely to happen because of hormones in emergency pills. Because of raised hormones (emergency pills), you may have pregnancy like symptoms which can be due to pregnancy too. Earliest you find pregnancy would be after 2 weeks of sex only by blood pregnancy test (beta HCG test). So it is better you wait for period patiently till your expected menses date and go for hCG test (around date of menses) or home pregnancy test (after 8 days delay in periods). Please keep on using barrier contraceptive devise these days and start Nuvaring after getting periods. If no periods, pregnancy test is positive, go for MTP. Consult a gynecologist. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Vasudha Jayant Athavale, General & Family Physician
