For your knowledge and future querries ,Nordette-21 is a combination drug that contains female hormones Ethinyl estradiol
that prevent ovulation.Nordette is very much effective as long as you take it the morning after you had an unprotected sex. However you can still take Nordette within 120 hours (5 days) of unprotected sex but the effectivity will not be that satisfactory. It may cause changes in bleeding patterns for subsequent 1 or 2 cycles. Dont worry ,as stress
can also alter cyclic bleeding pattern. So Relax and remember above points for next time.
Hope u got ur answer.
