What is the standard protocol for progesterone supplementation in a patient at 9 weeks gestation with a history of miscarriage and no active symptoms, when faced with conflicting recommendations to take dydrogesterone (Duphaston) once daily, micronized progesterone (Susten 200 mg) twice daily, or a combination of both?
For progesterone support at 9 weeks with a history of miscarriage, standard protocol typically involves using either oral dydrogesterone (Duphaston) or vaginal micronized progesterone (Susten), but rarely both together. Combining them is generally redundant and not standard practice. Either medication alone is effective, so a single, consistent method is usually preferred to keep your routine simple and stress-free. I highly recommend discussing this with your OB-GYN.
