6-12 days after sex and not every pregnancy has it. I actually think it pretty rare for it to happen.
I have exactly implantation bleeding im sure of it, I've taken three pregnancy test and all came up negative, how long should you wait to take another one?
it really depends on every woman sometimes its just a wipe and thats it.some women get it two days or just a day.And not every pregnancy has implantation bleeding
My doctor told me that implantation bleeding is very light bleeding and should only last for a couple hours.
