For a typical cycle, ovulation is roughly 14 days before the next menstrual period, although real timing varies. Conception can occur around ovulation, and sperm can survive for several days. The displayed fertile window is a simple estimate, not confirmation of ovulation, conception, or pregnancy. Clinical tests and specialist advice are more appropriate for these questions.
