Bleeding

Ok long story short my last lmp was 9/24/21. I got a positive pregnancy test 10/25/21 (faint) it continued to get darker so I scheduled my first exam . I started to spot red blood 11/6/21 and then bled heavy for 2 days and then spotting brown for a few days after. My hcg level was 122 and ultrasound showed nothing . Obviously thinking I miscarried. Here we are 11/17/21 and I’m getting positive tests. I’m nauseous , headaches and boobs still hurt. I’m going for more blood work tomorrow but has anyone been through this before. I know you can test positive for weeks after MC but my level was only 122 and it’s 10 days later with still strong test and symptoms ? 😩🤦🏻‍♀️
