MrsP777.. after u release an egg it needs to be fertilized with in 24 hrs b/c the egg dies after that. The sperm can live in a womens body for up to 4 days in the right conditions. After the egg is fertilized then it takes 6 days to get to the uterus and implant. That is why they say not to test until 12 dpo or later b/c it cna take alittle longer for the egg to implant.
