31 weeks, teacher, Covid cases

Hi All,

I have a question. I'm 31 weeks and a teacher in a high school. We all use masks and have gel. Ingound out we have a case am gst the students in one class I teach, and 10 are being quarantined and tested. I am not vaccinated, some of my colleagues are. We have about 3/4 weeks until holidays. Would you feel safe or ask for doctor's note to stay home?

Update: vaccination not available as I have been waiting ages and yesterday my doctor told me not to until after pregnancy.
