i thought i was "6 weeks" pregnant. my hormone levels are those of a 4 week pregnant person. The ultrasound showed nothing but they said that could be because it is too early. i have been bleeding for the past 4 days and sometimes big clots come out. They cant tell me if I have miscarried though because my cervix is closed and that means I am still pregnant. What is going on? has anyone experienced this that didnt have a miscarriage?
