About three days ago I woke up with the feeling of frequent urination and burning during. It kinda hurt in the lower regions before and after. Whenever I would go to the bathroom I would dribble blood, but it wasn't constant bleeding like a period. I am now due for mine and the bleeding is a little more heavy but doesn't seem to come out much until I go to the restroom. I have been PMSing and started to get small cramping. Is it just a wacked out period or something worse? (I've hardly been sexually active, no cumming, with protection)
