LADIES FERTILE WINDOW QUESTION

Are you still able to get pregnant a day before you ovulate as much as on the day you ovulate ??! Or higher chances are it’s better to BABY DANCE ON THE DAY OF OVULATION? If that makes sense..

I baby danced when I was having ovulation spotting I read online when you’re spotting during ovulation it’s the best time to conceive? I have irregular periods so idk if I even ovulate when this app says I do 😱

I also read on google that sperm can live up to a few days ?
