Hello doctor. Actually the intercourse happened on 25th of march which was protected still took unwanted 72 within 48 hours but after that no withdrawal bleeding occurred. My expected period date was 11th of april but on 8th of april I got some cramps nd bleeding started in the evening nd continued till 10th. But bleeding stopped on 11th. Though bleeding was heavy like my periods. I have done pregnancy test on 13th which came negative and today also I have done pregnancy test at home and it came negative. Is there any risk of pregnancy? As bleeding occurred earlier from my expected date.
