Did I miscarry?

I don't know if I was prego but there was a pretty high chance looking back on it. I was spotting for like a week was thinking maybe period but mine have never been that light and I had missed the month before but that's also the norm. but then I woke up in pain and covered in blood!!  And have been bleeding and in pain for the last three days. And I'm very tired and kinda weak in comparison to the norm. I feel like I might have miscarred. What are the chances? Thanks in advance.
