How Many days after ovulation, do you normally start your period? I am 8 days away from my period and don’t know if I haven’t ovulated yet!

Down below is when is “says” I ovulated... but I am just wondering when do you usually ovulated and how Many days later do you start your period? Because me and my SO haven’t had sex since the 20th and I’m afraid I didn’t baby dance when I ovulated!
