Hello doctor 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 stopped on 11th morning. After that I have done 3 pregnancy test on 13th, 20th nd 21th. Nd all were negative. Is there any risk of pregnancy? As my periods cycle is usually of 4-5 days. Nd bleeding occurred only for 3 days. Is there any risk of pregnancy? As bleeding occurred before my expected period date.
