Did I miscarry? Or am I in the process of?

I am 8 weeks and 2 days (first pregnancy). Yesterday I was having horrible cramping. It hurt to move, laying down made it worse, I thought something was really wrong. It was all on my right side (my abdomen to my right thigh and around to my low back on the right). I actually was considering going to er but it eased up a little after about 2 hours. And it got a little better by the time I went to bed. Today I had normal light cramping on and off but I’ve been bleeding a little and it’s brown. I just started bleeding a little red. It’s not a lot but still.... I don’t think this is supposed to happen. Any advice would be great. I am terrified. 😔
