Is pregnancy possible with sx on the 21st day of menst. cycle? I have normal 28 day cycle and would like to know this. What are the 100% safe days, if some one cud guide me to a chart that cud explain when sx can be avoided... sowmya replied. hi nandita, i don't think you can get pregnant on 21st day if your cycle is 28 days.try to avoid sex or use protection from 10 to 16 days of your cycle.it is an unsafe period if your cycles are regular and 28 days because you ovulate on 14th day of your cycle.3 days before ovulation and a day after ovulation are unsafe days if you dont want a child.so be cautious in those days.best of luck. Rose replied. If you have a perfect 28 days cycle, your chances of getting pregnant on 21st day are nil. You ovulate 14 days before your next period. You could get pregnant if your husband ejaculates inside you even 2,3 days before ovulation. Hope this helps you.
