Hello dear I understand your concern Your delayed period is due to hormonal imbalance caused by the I pill. I pill contain high progesterone and cause prolongation of second phase of the cycle. So it cause delay in period by 1-2 week. There is no chance of the pregnancy as you have did sex just 2 before the expected period date and it is completely safe period. Avoid stress, take healthy diet, drink plenty of water and do regular exercise Wait for the period to come. If it will delay by more than 2 week then consult the gynecologist. Hope this may help you Contact further if follow up needed. Best regards Dr. Sagar
