naintara, of course if you made sure the condom did not break when he took it off, the chances are zero. It does not matter what days of your cycle you had sex. The sperm is inside the condom and not able to get to your uterus.
If you have cycles longer than 21 days, you were anyway incapable of getting pregnant from sex on day 3 of your cycle, condom or no condom.
Take care.
