I think I got a concussion 6 days ago, should I call the dr or no?

6 days ago I got so drunk that I didn’t remember the last couple hours of the night. There was evidence (via bruises, soreness, and scratches on my Apple watch) that showed I must’ve fallen hard. I’ve been very tired and groggy and have had a constant headache since, until today. It finally started clearing up and I started to remember bits and pieces of the night. It didn’t occur to me until now that based on the symptoms and memory loss that I probably had/have(?) a concussion. Since it has been almost a week should I even call the dr? Or just leave it be since it’s getting better?
