Hello dear I understand your concern No chance of the pregnancy because: You have did sex on 2nd day of period: It is completely safe period as ovum is not released during this time so no fertilization will occur You also took I pill with in 48 hour sex. It also prevent the pregnancy. Your delayed period is due to hormonal imbalance caused by the I pill only. Period may be delayed by the 2 week. If period will not come after 2 week then consult the gynecologist for examination. Meanwhile avoid stress, take healthy diet, drink plenty of water, maintain proper pelvic hygiene and do regular exercise. Hope this may help you Best regards Dr. Sagar
