I have gone through your query and understood your concern. The high hormone content in the emergency contraceptive pill
disturbance. This can lead to withdrawal bleeding soon after the pill intake and/or delayed cycles. The medication prescribed by your doctor can be used as a cyclical course to regularize the cycles or to induce a period when there is a need. Usually, progesterone
alone is used to induce a period, but, with added estrogen
the effect is better though estrogens have more side effects. Hope your query has been clarified. Wish you good health.
