What Could Severe Headache With Dried Blood Inside The Ear Indicate?

I teach exercise in the mornings. I taught two classes today, cycle and silver sneakers (low-intensity cardio & strength). When I was finished, I had a pretty bad headache. That is common for me right before I start my period, which I expect to start in the next few days, so I came home, took a Goody s headache powder, and laid down for a nap. However, when is woke from my nap, I still had a headache and there was what I would consider a significant amount of dried blood just inside my ear. So much, that it had leaked out of my ear and there was some dried on my cheek as well. I ve cleaned it off, and it doesn t appear to be bleeding anymore, but I m wondering if I should be concerned?
