Covid concern

Hey everyone I have a serious concern.

So last November I got covid (from work and was out for a month)

I got vaccinated in February (not knowing I was pregnant)

I work full time at a nursing home and the place is lighting up like a Christmas tree with covid again. I’m due in 43 days and I really don’t want to get covid again or have to wear a mask during labor (I have asthma hard enough to breathe as it is)

What should I do? I don’t get paid maternity leave and I want to stay so I can get Fmla so I at least have a job
