I have no clue....I am thinking I do around 9-10dpo I don't have a clue though!
I found this....Generally, if an egg is going to be fertilized and conception is going to occur, it will have to happen in a 24-hour period after ovulation. The egg won’t survive in the fallopian tube much longer than this. Once the egg is fertilized, it will travel to the uterus for implantation. As it travels, it will continue to grow in size, its cells dividing and reproducing. The process of traveling and implanting will take somewhere around 7 to 10 days altogether.
