I am supposed to be nine weeks pregnant, but my hormone levels and ultra sounds only read four weeks. i started bleeding a few days ago went to the hospital and they told me either i am having a miscarriage or they miscalculated my due date the first time around. But now I have to wait a week to for them to tell me what is really going on. I was wondering if anyone knew any other possible reasons i would be bleeding other than a miscarriage.
