HI, thanks for using healthcare magic

Emergency contraceptive is approximately 88% effective in preventing pregnancy. Since you used it correctly it would significantly reduce the chance of pregnancy occurring.

Its use can alter the period either its timing or intensity. This may be the reason you are not noticing any indication of bleeding as yet.

If your period is delayed significantly however, it would be best to de a pregnancy test. These are accurate at predicting pregnancy if done 11 to 14 days after conception.

I hope this helps
