Hello! For The Past Week I Have Been Extremely Tired

Hello! For the past week I have been extremely tired - all the time - I don't even want to go out to parties, or do anything fun, really. I've noticed random reddish bruising on my arms and legs, in very peculiar patterns - no idea of how I've gotten them. And I've had severe abdominal pain, much like I did when I miscarried one of my twins about a year and a half ago. I've had a FEW nose bleeds - very seldom, but possibly noteworthy, and my blood pressure has been high enough to cause this and headaches. I'm not sure what is wrong with me and I'm too busy with work to go to the doctor. Do you have any ideas of what that could be, or how I could narrow it down more?
