positive opk help when to BD

hello, ive got the most blazing opk ive ever had this morning at 8.30, i can't stop looking at it 😍 when would be the best time to BD please, does it take 12-36 hour for the egg to release after positive, then does the egg last for 12-24 hour? so possibly i have up to 2 days to BD as much as we can for the best chance? thank you for your help
