Get busy at the right time Once you know when your egg will be released from your ovary, you can plan to have sex during your most fertile days: from three days before ovulation through the day of ovulation. You have a range of days for baby-making sex because sperm can survive for five to six days in your body. (Your egg survives for only about a day.) That means if you have sex on Monday, sperm can survive in your fallopian tubes, waiting for an egg to float by, until around Thursday – or maybe even as late as Sunday.
