Covid while 22 weeks pregnant

So I’m 22 weeks & 4 days & my boyfriends little brother who is 8 has Covid. He got it from someone at school & we think he’s had it for about 4 days now .. but just started showing symptoms 2 days ago. He could have had it longer because he said his friend at school has been sick all week.. I’m vaccinated but I am super nervous being pregnant & potentially getting it.. has anyone on here been vaccinated & pregnant & got it? My boyfriend & I have been trying to keep our distance but with 4 dogs & an 8 year old & we only have 1 bathroom.. it’s hard. 😫 this will also be my first time getting Covid, if I do get it.
