Cramping and Brown spotting

Veronica
Hi everyone.  I am 5 weeks 6 days today and I'm still continuing to have brown spotting and cramping for about 8 days now. My hcg came back at 6345 at 5 weeks 1 day and progesterone is 28. My dr said those are great numbers. I have a history of miscarriage so I'm just really worried. Has anyone ever had or is having these same things going on?
