My face won't stop bleeding?

I've had a little bump on my face (not a pimple!) near my temple for maybe a month now. It was very red but never hurt at all so I've left it alone. However, the other night, I noticed it started bleeding, a lot. If I left it alone for just a few seconds, soon enough the entire side of my face would be covered in blood. The only thing that stops the bleeding is leaving a band aid on it. Applying pressure and washing etc have not been successful at stopping it. And as soon as I take the band aid off it starts again. So today when I woke up it wasn't bleeding anymore. This started on Thursday night btw and today is Sunday. Then, without me touching it or anything, a few hours into the day it started bleeding again. This was around 11. It's 9 now and I just switched the band aid to see that it is still bleeding!! The bump has flattened out now but I just can't get this thing to stop. Should I see a doctor? It doesn't seem like a big deal but I'm a bit concerned that this is the 4th night now that this thing has been bleeding.
