4 weeks 2 days Brown spotting and cramps

I’m supposedly about 4 weeks 2 days and I’ve had cramping the last week and a bit. Today it was accompanied with brown spotting.

I worry because I had a chemical at 5 weeks a year ago and a missed miscarriage at 10 weeks 2 years ago.

These were my test results on Saturday , yesterday and this is this mornings after I started spotting.

I am getting my hcg checked and my progesterone today, but I’m just getting nervous. Should I avoid my workout ?
