Lucky guesses
We don’t think this is a series of lucky guesses, there has to be more to it than that. How could someone get their friend’s pregnancy right all the way down to the date of birth and gender? They must have been in some type of deal with this woman’s doctor.
Either the doctor was sending them information or they were running their own secret tests without her knowing about it. Or, they just guessed and kept getting it right time after time. Whatever the case may be, let’s just be happy that she had a healthy baby boy and nothing tragic went down.
