Growing more paranoid something will go wrong

I'm a worrier normally, but throughout my pregnancy I've been pretty chill. HOWEVER, this last month I've been so nervous that something is going to go wrong: that baby will stillborn, or unhealthy- or that something will go wrong during delivery and he won't make it or will be seriously sick. Does anyone else have these anxieties? Other than a random blip of high blood pressure once last week (which came down), I've been very healthy. I just can't stop the bad thoughts! 😥
