Hello welcome to the health care magic

The emergency contraceptive pill act immediately or by delay ovulation or changing cervical mucus consistency.

It is effective in preventing pregnancy by 95-97%

But it is not 100% effective.

So if your next period is delayed for 7 days than investigate with urine hcg card test to rule pregnancy

If you need to investigate early than blood hcg card test done

Hope your concern solved

Take care
