Ovulation confusion

I had sex 7 and 6 days before my ovulation, is it a high chance I could still get pregnant? Like I’ve read sperm can live for 3-5 days inside the vagina, but is it possible it would live 6–7 days and result in a pregnancy?

I took a Plan B the next day after sex, but I’m worried it won’t work. I know everyone says get on birth control, I get that and I will. I’m always careful, always always! This time went a little different.
