In the manner in which the intercourse happened and the fact that you had taken the emergency contraception
soon after, implies that you were adequately protected. The bleeding that happened after the pill intake was due to the withdrawal effect caused by the high hormone content in the pill. You may expect a period delay by a week or two and if you do not see your next natural period even after ten days after it is due, please get help from a specialist in person. Hope this helps.
