I have taken one emergency contraceptive pill 18-19 days before after sexual intercourse. After 6-7 days of taking this I started bleeding, 10 days earlier than my normal period schedule. First 5 days was like normal periods then continued as spotting for 4 days. After this for last few days again it has increased as normal period. Already it is 11 days adding Normal periods and spotting. Is it normal? How long it will go? What should I do?
