Spotting help!

At 5 weeks 3 days I started really lightly spotting sometimes it was brown sometimes it was light pink, right at 6 weeks it was more pink and a little bit heavier now I’m 6 weeks and 3 days and it’s just brown I would say heavier then spotting but not heavy enough to fill a pad. I don’t have a dr appointment until next Tuesday and when I called they said to just stay home it could be normal. I haven’t had any sever pain, a little bit of light cramping here and there no where near as bad as period cramps. The only pregnancy symptom I’ve had is tender breasts and the severity comes and goes. I’m really afraid of a miscarriage. Has anyone else had these symptoms?
