Very light brown spotting only when I wipe…..

Brittany

5weeks 2days pregnant. I have very, very light brown discharge. I only see it when I wipe. It comes and goes. Have had it on and off for the past 12hours. No pain or cramps. I still have my symptoms. Doctor is just going to have my HCG tested what’s other ways can I help make it completely go away? What are other causes besides miscarriage (Trying to be positive)? Thanks for your help.
