Excessive bleeding

Well, I went to the hospital two nights ago because I have been bleeding pretty much all of December, they did some blood work and all my levels are normal, including thyroid, hormones, iron, and hemoglobins. He put in a request for an ultrasound, but it could be a few weeks before they even call to schedule an appointment. The doc said he thinks its pcos, has anyone experienced this with pcos? When reading online (I know, bad idea!) I've heard it could go either way; missed periods or heavy. Thanks ladies!
