spotting at 6 weeks. hoping not another miscarriage

I have definitely been having pregnancy symptoms, but when I got home from work today I saw I had spotted. It was brown spotting like I was about to have my period. I experienced this, this past winter but lighter spotting than this one. Turned out to be a miscarriage. Anyone else with brown spotting and still had a normal pregnancy afterwards. I am so worried that I'm going through another. 😢
