Bridgerton has made some surprising book changes over the years - including cutting Francesca's pregnancy and miscarriage from the story. During season 4, which concluded on Thursday, February 26, Francesca (Hannah Dodd) mourned husband John's (Victor Alli) death while briefly assuming she was pregnant. Francesca was forced to undergo an exam, which is when she found out she wasn't expecting a baby. The revelation was a departure from Julia Quinn's When He Was Wicked where Francesca miscarried weeks after John's death.
