Hi,
Unfortunately even the pull out method doesn't give you absolute protection. In fact the statistics are about 1 in 100 women about 1% will get pregnant using the pull out method. So while this isn't a strong chance there is still a chance.
Women ovulate 14 days after the last menstruation so that puts your ovulation date at 18th. Though keep in mind women can ovulate a few days before or after and semen can live as long as 5 days.
