Hello, I Passed Out Yesterday And Fell Face Down, Hitting

hello, i passed out yesterday and fell face down, hitting my head on hard floor, it was a pretty bad fall. I woke up with the area on my forehead swollen a little, and over time i noticed now there is like a dent in that area. When i touch it, it sinks it and it feels like there's fluid inside of it. I'm scared this might be a possible hematoma, but im sure i didn't fracture my skull. What do you think this is ?
