Pregnant and working in preschool

Hi everyone,

I am currently 10 weeks pregnant and I work in preschool. I have been sick twice so far and it has been a living hell. I have read some research about covid possibly causing miscarriage in early pregnancy and of course there are many other viruses that raise my concern.

Was anyone in a similiar situation and how to keep a healthy pregnancy especially with other pregnancy symptoms including nausea, fatigue etc.
