Talk to Gynecologist on Pregnancy

I am 11 weeks pregnant with history of miscarriage. Miscarriage ki wajha se mei bohat paranoid rehti hun is liye har 10-15 din baad ultrasound kerwti hun. Mei ne 9 weeks mei ultrasound kerwaya tha. Mujhay doctor ne kaha tha 11-12th week mei eik ultrasound lazmi hota hai. Mei 11th week mei ab dubara ultrasound kerwa sakti hun? Also yeh normal hoga ultrasound ya kuch specific? Doctor ne likh k ni dia hua kuch b. Jaun gi tau fee dubara deni hogi. Ultrasound kerwa k jana chahti hun. Pls tell k ultrasound normal jo pehlay kerwati hun wohi kerwana hai fetal well being ka???
