Not perfect: Some women can ovulate during the week of menstruation, some as late as day 19-20. The human body isn't perfect, so i typically tell women who don't want to get pregnant that there is no 'safe' day in one's cycle. There are apps you can download which can track your ovulation so that you have a better understanding of your cycle. Being off a few days is definitely okay!
