Should I tell work?

C

I had a miscarriage in June which was of course devastating.

I just found out that I am 3 weeks 5 days pregnant now which is so great! But now I’m scared something will go wrong.

Which is normal and I guess I can deal with, but I am a teacher and where I live, we get paid preventative leave because Covid is a risk to our pregnancy.

But this would entail telling so many people about the pregnancy and I am just so scared because its so early. I could have a chemical pregnancy or a miscarriage like last time... it makes me want to just wait another week or two to see, but maybe I should just go through and have faith in this pregnancy.

Any advice??
