Is my wisdom tooth extraction healing?

Okay, so I got one wisdom tooth removed on Tuesday so that's five days. I am really worried I might get dry socket. I have been following the doctors orders but I made a mistake today and drank out of a straw, now my blood clot is hanging loose and every time I breathe there is a small pain. My gum is whitish grayish and the clot looks blackish/grayish. I cannot call the Dentist because they are not open on Sundays. Someone please help! :( I really don't want to get "Dry Socket"
