What Is Implantation and When Does It Happen?
Implantation is commonly described as the process where a fertilized egg attaches to the uterine lining. Timing varies, so calculators usually provide a window rather than one exact day.
Typical Timing Estimate
Many educational estimates place implantation about 6 to 12 days after ovulation.
Why It Is a Window
Ovulation timing can shift, conception timing may be uncertain, and implantation does not happen at the exact same time for everyone.
How It Connects to Testing
Pregnancy test timing depends on hormone levels rising after implantation. Testing too early may produce a negative result even when a period is not yet due.
