Still afraid

I am currently 16 wks pregnant but I am still afraid of the change of miscarriage.. A few of my friends had lost their babies even around 18 weeks or after. I have only been to the dr a couple times and everything is said to be normal so far... She didn't really go over any of my blood results so I'm thinking that means everything came back normal... I am going for an elective scan soon and I am just nervous. I have been feeling baby move too so I know it's alive in there! I guess I am just still afraid something could go wrong out of no where 😓 anyone feeling a similar way or know how common it really is to lose a baby that late in pregnancy? Please no scary stories lol I don't need more anxiety!
