Question About Duphaston

Hi, can I ask what medicine does doctor provide usually during the first trimester? Doctor prescribed duphaston even when I do not have any spotting issues but read about the many side effects. Hence unsure if I should take it. First gynae I visited gave me folic acid and vitamin D to be taken daily. Second gynae suggested to take folic acid daily but vitamin D to once a week and prescribe additional duphaston. #1stimemom #advicepls
