My understanding is that it's not a real, scientifically defined term. It just kind of loosely refers to a pregnancy that is lost not long after a woman would normally get her period... so it shows up on an early test, but would otherwise be mistaken for a slightly late period.
Thanks for clearing this up for me. My peri said I still had a chemical pregnancy if I was to have a mc when I talked to him last week, and I was just a little confused as to the term and if he will still consider it that today when he calls. Thanks!
