Wow, so excessive dryness can cause that much blood?!
I figured it was probably nothing to really worry about but when you see a lot of blood coming out of an orifice (and not just any orifice but one of your own) it's hard not to freak out a little.
I plan on going in to see the doctor next week...unless I have no more problems, in which case I'll skip it (I'm still pissed off from my last appointment).

Thanks for the advice!
