Pregnant Nurse in LTC facility

Currently working in a long term care facility as an RN. Almost at my second trimester. In the beginning of the pandemic, there were several women pregnant and they did not have to go near + or suspected covid patients. My DON knows I'm pregnant but has not told me to stop taking care of possible or + patients. My N95 doesn't fit. My OB at first said to use PPE, and I have another call out to them today to inform them my whole unit is on precautions for possible covid. Curious to see what other OBs are saying to pregnant nurses right now?
