When did pregnancy get defined as when the zygote implanted on the uterus lining?

I don't like your new blog format (including the last couple): too typical of other blogs. I liked your original and 2nd generation (few months back; with the Vatican background).
It's better when it stands out. Sort of like my teeth. (Only kidding … about my teeth.)

All the papers I've read thus far refer to possible "post-fertilization" effects of EC, so failure to implant properly is covered even if the author's don't consider carrying a pre-implantation embryo to be a pregnancy.
