Hello dear
I understand your concern
Do not worry.
Pregnancy is not possible in your case because:
1. You have did sex on 23rd day of cycle and it is complete safe time. (because no ovulation occur at that tome)
2. Again you took
I pill immediately after sex and it is very effective in preventing the pregnancy.
It has just 0-3% failure rate.
Your period is delayed due to the
hormonal imbalance caused by the I pill.
I pill contain high
progesterone and that cause prolongation of second phase of the cycle.
It cause delay in period by 1-2 week.
Period may be associated with excessive bleeding.
Meanwhile avoid
stress, take healthy diet, drink plenty of water and do regular exercise.
Hope this may help you
