Actually please I’m scared

I’m so scared, I started feeling sick like a couple days ago (maybe 3 or 4 days ago) and I thought I just had a cold, but I woke up a couple days ago with a sore throat so I took a picture and seen these weird things at the back of my throat. I’ve tried googling everything but nothing is helping bc I don’t know and nothing looks like what the things in my mouth looks like. I don’t have much symptoms apart from a blocked nose and sometimes a fever, and my throat dosent even hurt it just feels dry and scratchy a little so I’ve been drinking water but idk what this is I’m scared
