I used the nuvaring for 3 cycles. When it was time to put it back in, I forgot it in the car in 99 degree weather for about 6 hours. I did not put it back in. I Had unprotected intercourse 9 days, 12 days and 13 days after the day my ring was "supposed" to be inserted. What are the chances of pregnancy? My period is due in about a week and a half. When can I test if pregnancy is possible?
