Husband got covid

My husband tested positive for covid last night, I tested negative. He’s been quarantined to our room upstairs and I’m on the main floor with our two year old. Obviously I’m pregnant and very nervous about getting it but basically having to accept that I probably will. Anyone else dealt with this or having to deal with this? Any tips? Husband and I both were supposed to get our second shots in a week. Hopefully having one shot will help? I dunno. My mind is reeling.
