Bleeding at 10 weeks

Elisa • Mon, Sep 21

Well my last period was July 10. In late august I was spotting just brown it looked like implantation bleeding. Then last night September 20 I started spotting brown right before bed. When I woke up my pants had blood on them and since then its been bleeding constant . no cramps or clots though. Is there any reason it would be heavy other than a miscarriage?
