User blog:Lilydreaming13/errors of fanfictions

I'm new to the wikia, and I do not want to sound arrogant and presumptuous, but I happened to read the fanfics with errors, not grammatical errors, but errors on a certain topic on pregnancy .... 1, the girl should take the test after 3-4 weeks of the relationship, and not the next day, at least the guy is not an alien 2nd baby's sex is not known until the 3-4 month, if it's a girl you have to wait longer 3rd you can not feel the baby move until the mother is not swollen like a balloon for now I can think of only these :P  and you have never read any fanfiction with these errors or with others? or on another topic I repeat do not want to be presumptuous  :)
