question

so we had sex all those days and expect on the 22 he didn't finish in but the rest yes. on the 29 we didn't have sex nor today when I'm ovulating. how long does ovulation last? he gets home at 12am that's why I ask. & Do you think I could get pregnant from any of those days that we did have sex? this app say I don't start my fertile sundown until the 9th to the 15 but I'm already had the egg white cm plus today I saw like a milkey white cm on my underwear is that due to ovulation?
