Urethra ripping

This morning I noticed a small amount of blood (1 or two drops) on the head of my erect penis. It seems to be coming from the urethra which looks like it's ripping a little bit. The bleeding stopped when my erection went away, but I'm still very concerned. I'd go to a teen clinic, but they're all closed because it's a long weekend. What should I do in the mean time?

Oh, and to top it off, I was probably going to lose my virginity to my girlfriend tonight, but that doesn't really sound like a good idea now that my dick's bleeding.
