Hello;
welcome to HealthcareMagic
You have taken Nordett fery late so whether it will be effective it is difficult to say but practically no.The withdrawal method you used does have comparatively less chances but you should have taken nordett immediately after sex.Once the time goes off nordett is not very effective but please see if you have withdrawal bleeding with in 8 days of taking nordett ;if you have then no reason to worry or wait for your expected date to come.Do not get stressed as the periods may get delayed due to stress.If you do not get periods then do test for
pregnancy.
Thanks
