Duphaston 3x a day???

Hello mommies, im 6 weeks preggy and my OB prescribed me duphaston 3x a day for 2 weeks and hemarate Fa, I also had miscarriage 6 months ago. Any one here na same situation with me. Lahat kasi ng nababasa ko 2x a day lng and yung iba if needed lng talga. Medyo curious lng ako yung ob ko kasi biglang nagka emergency kaya hindi kami masyado naasikaso niresetahan lng ako.
