Terrified of first scan!

Chloe • 2 angel babies 😇 😇 ❤️ 1 baby on the way 👶 💕

This is my third pregnancy. First ended in MMC, 2nd was 7 years on and a chemical at 5 weeks, now I'm 11+5 and dating scan Friday. Have had all morning sickness symptoms and sore nipples and exhaustion.. but terrified of first scan that it'll be bad news. Chances of a third loss? :(
