Brief Answer:
A side effect of morning after pill.

Detailed Answer:
Hello dear,
Thanks for trusting hcm about your health care.
I have gone through your history and understand your concern.
The morning after pill contain high doses of hormone in it and can cause hormonal imbalance and menstrual irregularities.
So your period maybe delayed due to side effect of a pill.
If you missed your period by 7 days than get your a home urine pregnancy test to rule out pregnancy.(though the chances are quite low).
Hope found useful,feel free to discuss more information.
Good luck.
Regards
