What is the earliest Implantation can occur?

Question: I have been trying to find the info on the internet and I'm finding all different things. Some say anywhere from 4-10dpo, others say 6-14 dpo. Can implantation occur at 5dpo?

Answer: The "norm" for implantation is 6-12 days after ovulation. But every woman is different so implantation 3-5 days after ovulating cannot be ruled out, nor can 13-15 days after ovulating. Add: But the day you conceive is not easily known, actually the only way to definitely know is having the sperm injected into the egg by hand. So you can only go on your ovulation day and period due or implantation bleeding if it's experienced. So implantation days need to be a large range, you conceive the day of sex or up to 5 days later, so it can be 5 days before the egg travels to the uterus, delaying implantation. So to implant 5dpo, sex was on ovulation day, conceived hours after sex not days.
