So I'm a book editor. And I had to explain to a full grown man that women do not get their periods while they're pregnant. He had a pregnant character and there was some plot point for drama where she starts bleeding and they think it's a miscarriage. So it's this big sort of emotional thing. And the plot point was explained by it not being a miscarriage, but being a period, and she's like, eight months pregnant or something. So, I came back with all these suggestions. I'm like, "There's other reasons why she could be bleeding, can't be a period though. Like just anatomy. This is how it works." And he literally sent me a long, detailed email about how, yes, women do have their periods while they're pregnant. This man was like 50.
