On 2nd Feb I Had Period And On 4th Day

On 2nd feb i had period and on 4th day of period i.e 5th of feb we had sex. I took contraceptive i pill on 6th feb which is almost 10 hrs after having sex. Then after 8/10 days of taking pill I bleed. It was for 2/3 days (very light bleeding though). Now its been already 1 month 14 days my last period was. I did pregnancy test though kit at home. It showed negative. Is there still chance that i am pregnant.
