Bleeding at 8 weeks ( TMI PICTURE)

For the last few days I’ve had some brown to bright red bleeding on and off. I followed up with my Doctor Who did an ultrasound and we saw the baby. Heart beat was at 139. Doctor called it a threatened miscarriage and is having me follow up with a high risk ob tomorrow. The bleeding is off and on throughout the day. Some of the bleeding is very sticky mucus like. I also have these things on the toilet paper. It almost looks like rolled up small pieces of tp but orange/brown. In the picture below shows what it looks like sometimes. Today it was like this but much more red. Anyone go through this? Stories, outcome etc? I’m going on vacation next week and I’m so worried.
