Covid and pregnancy

Hey so I’m a daycare teacher and was recently alerted by a parent that an email was sent out about an employee testing positive for Covid. The daycare said they’ll get the building professionally cleaned but none of the teachers were made known if they were in contact with said staff member. Im 16 weeks pregnant and don’t feel comfortable going back until I know for sure I don’t have it and that everyone in contact is quarantining for 2 weeks...what should I do ?
