Preparations containing progestogens are considered safe in pregnancy. Sometimes, like other medicines, they may or may not result in side effects in the woman who uses them, which may depend on the dose. Fewer side effects are generally observed after vaginal administration than after oral administration. I can provide such information from a pharmaceutical point of view. Please note, however, that we cannot review medical recommendations or confirm what the doctor may have meant. In selected gynecological cases, simultaneous administration of progesterone in vaginal and oral form is practiced - the decision along with the determination of doses is made by the gynecologist. However, in case of doubt, it is best to contact directly the doctor who examined you, had information about the course of pregnancy and about the Duphaston preparation already taken, and recommended a combination of Duphaston and Utrogestan. You can also consult another doctor: https://www.gdziepolek.pl/telekonsultacja I enclose additional information about the preparations you are interested in: https://www.gdziepolek.pl/produkty/25619/duphaston-tabletki-powlekane/apteki https://www.gdziepolek.pl/produkty/81108/utrogestan-kapsulki/apteki
