I have gone through the query and understood your concern. Emergency contraceptive pill
, when taken prior to ovulation, inhibits ovulation. Thus, pregnancy
cannot occur. The discomfort could be due to the increased pelvic congestion as a result of the high hormone content in the pill. Sometimes, cyst
formations are observed in the ovary. Your next natural period also may get delayed by a week or two. If the pain is persistent and annoying, if you become overdue by ten days, please see a specialist for further support and management. A sonogram of the pelvis, preferably in the trans-vaginal route, is most helpful. Hope your query has been clarified. Take care.
