Hello Thank you for your query. The medications being given are forms of progesterone since you are having bleeding, which is a sign of threatened abortion. Duphaston is banned in certain countries, because of some reports of adverse effects on fetus. You can discuss with your gynecologist regarding switching over to natural micronized progesterone, which is safer. Otherwise the medications are safe and advisable with your picture. Also, take plenty of rest, avoid sexual intercourse, and do not stress out. Take care.
