4 weeks pregnant and wish I could work from home...

My first round of ivf worked! I am currently 4 weeks pregnant, and would love to be able to work from home due to the Coronavirus (schools etc are all closed in our town).

I don’t want to tell my office that I am pregnant this early, but am seriously concerned about being around people now that I am pregnant.

(I currently don’t have at home capabilities).

What should I do? Is anyone else worried about this?
