When you are becoming pregnant when is the beginning of implantation and when is implantation complete?

Implantation happens on the 16th day after ovulation. You might get cramping and some spoting but not everyone get the symptoms.. I know i had no spoting with my first and i had my implantation 2 days ago with no spoting. So it takes 2 to 3 days for completion..then you can test next week when your period comes on. good luck
