Pain and blood

So just recently (like 8 or so hours ago) I went to the bathroom. Peed, looked normal, stung a little to pee at first, then wiped and there was blood. I figure, "Hey, I'm spotting, no big deal." put a pad on just in case; there was nothing when I went to the bathroom again. Peed, hurt to start, wiped, blood. "What the hell?" So just for sh**s and giggles, I washed my hands and inserted a finger and there was nothing, well no blood. No blood coming from the vagina itself. I figure, maybe my boyfriend fingered me a little too roughly, so I tried looking in a mirror to see if there was any like, surface, damage, I want to call it, and there was none. It stings (no agonizing pain) when I start to pee (then it goes away), and when I wipe, there's blood.
Sorry, but um, wtf?
