I know this is so gross and unrelated but hear me out

Okay so I've had the flu and I have this cough that is disgusting but now all the crap in my chest is coming up so when I cough I can literally feel the mucus come up but I don't know what to do with it so I swallow it. I know it's disgusting but like, it's disgusting nomatter what. Is it bad to swallow it?
