Coughing up yellow phlegm with red chunks in it, sore throat and feeling sick.

Well my throat has been hurting for the passed 2 or so days, and yesterday it felt like I was catching a cold really bad (getting goosebumps feeling like i was cold but also feeling hot at the same time, heavy fatigue, mild nausea) But today I kept feeling sick on and off, but not as bad as the day or night before; the same with my throat ache. But the phlegm has been a persistent thing.

Also I haven't been really able to smell out of my nose unless it was a really strong smell regardless of it seeming like it was clear of mucus or not (not being able to smell well has been happening for a couple months, but that's probably just allergys (allergies) or maybe swollen nasal passages?)
