Bridgerton Season 4 Reframes Francesca’s Pregnancy Arc, Skipping the Book’s Miscarriage

Bridgerton Season 4 changes Francesca’s pregnancy storyline from Julia Quinn’s When He Was Wicked by having her and her husband face infertility, moving John’s death earlier in the season, and showing Francesca learning she isn’t carrying the Kilmartin heir. Showrunner Jess Brownell says the miscarriage felt too morbid and the shift preserves the tone while honoring fertility themes; author Julia Quinn supports the adjustment, noting Francesca’s emotional arc remains true to her experience. The creators also indicate fertility will continue to be explored in future seasons.
