Worried n fear everyday.

Hi everyone, I had a missed miscarriage last yr n I'm week 8 pregnant now. Everyday feeling worried n fear that I might have another miscarriage again or what if baby is not healthy. Gynae gave me duphaston to take becos of my miscarriage history. Anyone took duphaston will it really stabilize your baby or some take and still get miscarriage? I do not have any bleeding..and 1st pregnancy n now I don't really have morning sickness or any symptoms only feeling bloated and abit of mild nausea that's all
