Hi,
I understand your concern.
11th day of menses cycle can be considered as a fertile day.( Normally ovulation day is on 14th day in 28 day cycle. & sperms can survive for 3 days maximum & can cause fertilization of ovum on 13th - 14th day.
* Nordette is a combined oral contraceptive ,taken cyclically for contraception. If you have taken Nordette in higher dose as an emergency contraceptive ( 4 pills after sex & 4 pills again after 12 hours)- It will prevent pregnancy. & periods would follow,though the cycle will be disturbed.
But if you have taken inadequate dose , you need to exclude pregnancy by pregnancy test.Positive test demands MTP to avoid fetal abnormality.
Thanks.

HI, thanks for using healthcare magic

The use of emergency contraception can cause irregularities in the following menstrual cycle.

Emergency contraception should be effective if used within the first 24 hours.

A pregnancy test can detect pregnancy by day 11 to 14 after conception so if this time has passed then you can do it at this time.

I hope this helps
