, a progestogen and is effective if used within 72 hours of unprotected intercourse
. Since the pill disturbs the normal hormonal
milieu of the body, withdrawal bleeding is usually noticed about one week after the intake of the pill. Also, the next normal period usually gets delayed by about 10-14 days. If you do not see your next period even after 10 days after you are due, see a gynecologist for further appraisal of the situation. Absence of ovulation means that you are in the safe period and you do not need a pill then; the pill is effective during ovulation. Hope this helps.
