Scared!! 😢

I'm 10wk pregnant and I am as happy as I can be!! HOWEVER, the past few weeks I had 3 of my friends who aswell where pregnant miscarry one at 15wks, 8wks, and the other a stillborn at fullterm. I am terrified this will happen to me! I know miscarriages cannot me prevented but what can I do to make this process as safe as possible for the baby and myself? What can I do to keep my mind off negative things? Please help!
