Miscarriage?

Hi guys.

Trigger warning but I will be speaking about and showing photos of what I can only assume is a miscarriage.

I’m 8 weeks pregnant, I’ve actually had a scan 2 weeks ago and confirm this, but I started bleeding Thursday evening and it’s not stopped since. I’ve had back pain, not any abdominal cramping really. It started as pink when I wiped, then it started to get dark red, then it was fresh blood. It’s not heavy but I have to wear sanitary towels in my underwear. I don’t have any pregnancy symptoms and I don’t feel well in myself to be honest. Does this sound like I’m having a miscarriage? It confuses me that if I am losing the baby, why it hasn’t passed yet.

Thanks in advance. I’ll share the image I have below.
