Hello dear
I understand your concern
You have taken Postinor 2 with in 24 hour of the sex and it is highly effective in preventing the pregnancy.
It has just 1-3% failure rate.
Bleeding few days after is breakthrough bleeding due to progesterone withdrawal effect.
Your period will come early is again due to hormonal imbalance caused by the postinor 2.
Your delayed period could be due to hormonal imbalance.
Pregnancy test will give sometime false positive result.
I would suggest to consult the gynecologist and undergo proper examination and blood HCG, reproductive hormone analysis.
Period can be induced by the progesterone pill in absence of the pregnancy.
Avoid stress, take healthy diet, drink plenty of water and do regular exercise
Hope this may help you

Best regards
Dr. Sagar
