please help me get over my anxiety

ok so I got 2 positive urine pregnancy tests and I'm 8 days late. yayy :) I go for my blood test on Monday. I'm happy and excited but I'm really really scared of miscarriage. this is my first time being pregnant so I really want this. for some reason all I can think about is miscarriage only because the few people I told had miscarriages and they scared me! I think I'm stressing myself too much about it. does anyone have advice to help me get over this? I want my first pregnancy to feel happy not so scared.
