When Does Implantation Occur. Hence the name implantation. Some women can take longer or have implantation earlier.
In the majority of successful pregnancies implantation occurs between 8 and 10 days past ovulation DPO with 9 DPO being the most common. The site of fertilization are the fallopian tubes and development takes place in the uterus. Sometimes however implantation may occur between 6 and 12 DPO although the chances of it happening before 8 DPO are slim.
Implantation usually occurs about 6 to 10 days after conception and although this might seem incredibly early knowing some of the signs of implantation can help you determine when to take a pregnancy test to get the most accurate results.
After ovulation it takes 7-9 days for the fertilized egg to travel down the fallopian tube. So the exact date of implantation can depend on when you ovulated and whether conception occurred early or late in the ovulation window. This is known as implantation bleeding. Even though implantation is known to occur as early as day 6 past ovulation and as late as day 12 past ovulation studies show the implantation window most commonly occurs during days 7 to 10 past ovulation with day 9 being the most common implantation day.
