Hello, I have gone through your query and understood your concern. The emergency contraceptive has a high content of progesterone and this causes the increase in the vaginal discharge. Since you took the pill soon after the intercourse, you are very well protected. Moreover, if the intercourse occurred during the safe period, you are protected naturally. You may see withdrawal bleeding a few days after the pill intake. Your next natural period may get delayed by a week or two. Please see a specialist for further management if you become overdue by ten days. Hope you find this information useful. Take care.
