Girl talk: My period only lasts 3 days...is something wrong?

Hey girls (and guys, I suppose, if you’re curious about this sort of thing) – I’ve always thought I was just blessed with short periods, but the other day I wondered if something might be wrong. Seriously – 3 days and that’s it. Granted, the first couple of days really suck – got the cramping and mood swings and everything that goes with it…but then it’s done after 3! I’m always pretty regular too, every 28 days.

Could this be an indication of something worse in my body?
