Anyone get pregnant with only having sex cycle 3 days prior to ovulation

Am

I know sperm can live up to 5 days so I know it’s possible. Just looking to hear from personal experience. We had sex 3 days before ovulation (based on glow prediction and a positive opk, not confirmed with bbt. Had sex again the day after ovulation. We aren’t trying but not preventing either. We have 2 sons already, and even tho we haven’t been sure we wanted a third I find my self really hoping to be pregnant again.
