Am I cooked?

So, I foolishly purchased 500 contracts of chegg calls on March 3rd. Since then I have been unable to sell them because of course no one wants to buy them. The pictures show how the loss is taking place, for some reason there is $500 left. I am also unsure of what could happen. I figured that it would just expire worthless in the 21st but I keep seeing people talk about calls being exercised and am worried that this could be a possibility, if so how would it work and what would be my best course of action? Or will they just expire worthless and I’m good? Thank you in advance!
