When is the earliest implantation can occur?

[carebear1805]

Just wondering if anyone knows when the earliest implantation can occur? I have always read 6-10 day can it happen any earlier?

I've never heard any sooner than 6 days personally. I would say that's the earliest it can happen.

Thats what i,m thinking. I just Google it and saw a lot of things saying as early as 4dpo.

The doc said I had implantation bleeding :/ and I was 5/6 weeks gone

[NicMom]

I thought it was 5 days.

I've read as early as 4 too :-) but From my research it's rare, but possible
