ovulation info

nys

so i have noticed people giving information about ovulation 12-24hr AFTER you have a positive opk? i’m new to this. so if we made love on day of ovulation, and sperm can live up to 5 days, there is still a possibility? i am sorry. i am so new to tracking, learning about my body. just really want to get pregnant lol. which i’m sure we all do. any info i am open to receive. ☺️
