I could be misremembering but I think Anna shared her reaction to finding out she was pregnant in that first trimester vlog - as in she had just taken the pregnancy test and then filmed her reaction. I think that probably counts as oversharing. I mean, shouldn't that have been a private moment? Then again, she went into detail about the conception on the podcast. She massively overshared with her 'crying after sex' comment, while Lily just sat back and laughed. I'm sure there must have been more oversharing, but I can't recall. She was also super smug in that video re: hiding her pregnancy from viewers, saying that kids were something that might happen 'one day' when she was already pregnant etc. Guess what, Anna? We knew you were pregnant MONTHS before you announced it!
However, I think the real reason she made that video private over all others is because of the 'karma' comment. She has to have received some negative feedback for that one! At least I hope so!
