7 weeks & bleeding please help.

Mary
Went to my dr today for the very first check up. They took a bunch of blood but I could possibly of had a mc. 😔 I'm bleeding dark red blood with clots consistently yesterday and today. Dr said it sounds like mc but is doing a whole bunch of blood tests to check my levels. I still have pregnancy symptoms (which is a good sign he said) but I'm still really scared I'm gonna loose the baby :( has this happened to anyone else? This is my first time being pregnant.Â
