Thanks for posting your query
You are absolutely right, this condition is due to excessive preoccupation about the pregnancy
Your concern is genuine and would help for to be protective but at times too much of a good thing can also be bad.
Pregnancy itself causes mood swings and anxiety
So the two factors combined can make you sick.
You have better consult a psychiatrist
and learn relaxation techniques
that can be practised during pregnancy.
