Hello dear I understand your concern Your delayed period is due to the hormonal imbalance caused by the I pill. I pill contain high progesterone and it prolong the second phase of the cycle. Period may be delayed by the 8-10 days. Avoid stress as stress itself cause delay in the period. Pregnancy chance is less a you did sex in the safe period of cycle. If period will not come then other cause of delay period like ovarian cyst, endometriosis and adenomyosis should be rule out after consulting the gynecologist. Take healthy diet and fresh fruits like papaya, orange and pineapple. Do regular exercise. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
