Last year I had miscarriage,  after 9 months got pregnant again. Currently 9week is running. At 5week Doctor suggested me to take duphaston once in a day and  other doctor suggested me to take susten 200mg twice a day.  I started with sustain 200mg twice in a day and went for checkup at 8.2week. I don't have any spotting or any white or blood discharge, doctor who percribed duphaston asking to take duphaston and sustain is optional and other one said take both.  I aim confused about dosage of medicine.  Not sure sustain is required with duphaston or only duphaston is sufficient. Should I continue with sustain or duphaston or both.
