Possible miscarriage...

Woke up this morning to a lot of blood in my underwear. I went to the bathroom and basically filled the toilet with bright red blood. I had no cramping and the bleeding slowed down to a stop. Took a shower and called my doctor. Bleeding just picked up again with light cramping. Bleeding isn't as bad as the first but it's there. Waiting for my mother in law to pick up my step daughter and then we're headed to the er.
