What is going on with my throat ??

I recently got the Covid vaccine a couple of weeks ago and I was fine until my mother went to work and caught it while I was home! She has been having a very hard time however on a scale of 1-10 I would say I’m a 6/7 I just have a runny nose and mucus cough but the cough came after I found out she tested positive but my issue is that I have been cough up phlegm with broke spots in it! They said this could be a fungal infection on Google but I recently have quit smoking a couple weeks weed ago as well

I am going to the hospital in the morning but I thought I’d hear a couple of you guys opinions out 💕
