Hi, I am 6w1d pregnant. I have brown discharge with no smell no pain for 1 day. I am taking 75 mg baby aspirin and 400 mg progesterone daily?

Probably normal. The cervix is very easy to bleed during pregnancy so any bleeding may collect in the vagina and over time turn brown. Signs of miscarriage include bright red vaginal bleeding accompanied by rhythmic cramping similar to labor pains.
