Anxiety...

So I’ve seen so many stories on here where families lost their baby at 16,17,18 weeks or so on and don’t get me wrong my heart goes out to them, but those stories give me anxiety so bad....I’m currently 16wks 2days with a sweet baby boy and I am so scared of losing him. I always try to think positive and that it’s rare to lose him so late on, but my anxiety takes ahold of me. Please give me some positive advice/stories/vibes...I’m anxious and scared... Everything has been great this pregnancy besides my sickness...
