The Swedish royal couple are on a two-day visit to their dukedom, Värmland, and are expected to carry out engagements in Arvika, Eda and Karlstad.
The palace shared in a statement on Monday that the princess is "doing well" and there are no changes to Sofia's autumn schedule.

Prince Carl Philip and Princess Sofia, who are already parents to Prince Alexander, eight, Prince Gabriel, seven, and Prince Julian, three, will welcome their fourth baby in February 2025.
The announcement came just two days after the couple attended Princess Märtha Louise of Norway and Durek Verrett's wedding in Geiranger, Norway.

The couple began their visit to Värmland by attending the inauguration of Volvo's new Construction Equipment building in Arvika, where they were greeted warmly by employees upon arrival.
Sofia, who wowed in an orange and white ombre dress at Märtha Louise's wedding, looked chic in a white boxy-style top with black wide-legged trousers. She donned a blue patterned scarf upon arrival and styled her brunette locks in loose waves.
