There are charities that take cut hair to make wigs in this country too (the Duchess of Cambridge donated her hair when she had quite a haircut), but the person in question didn't have particularly long hair anyway! Also, I don't think they take dyed hair.

The pregnancy thing is just WTF: people being coy about pregnancy (and what in any of her writing over the years suggests she would be coy about it anyway?) tend to be a lot more twee (and more obvious).
