Help?? January 8th

I took a test January 1st and got a faint positive I took another the next day and got a better positive. I weigh between 85-90 pounds my mother was always very petite ,I had been having a stressful week and January 7th I had tight cramps all day. January 8th I started bleeding and it just got heavy as the hours passed. From what I can remember my last menstrual was November 27th. I wanted to say I was maybe 6 weeks ,I can’t tell if it was just a natural miscarriage or a chemical as I was two months apart from my sisters miscarriage and she had to have a d&c. February 14th and still no period?
