Is this normal?

I’m a little concerned I have have brown spotting on and off for 4ish days. I had a miscarriage back in December so I’m terrified at any spotting also don’t have any symptoms which is scaring me. I been having cramps too. I’m 6 weeks today and got this when I wiped. I also had pink/red spotting last night. I won’t see my doctor again until 3 weeks.
