I had a missed miscarriage about a year ago. In december 2013 again I got pregnant and dr. gave me duphaston 10mg twice a day orally. After three days I got my period and it was very heavy with bad cramps. Now again I am seven weeks pregnant. I had my first ultrasound in 6 1/2 weeks. Everything is normal. Dr. gave me duphaston 10mg to take orally. I am very scared now as I think duphaston is not suitable for me and my baby. I have next appointment on 16june 2014. I am also taking calcium, d3, vit e, vit c, vit zinc, folic acid since my last period that was on 7th april. Please suggest.
