Should I worry?

Mallory

I had a light amount of brown discharge when going to the bathroom yesterday and it went away. Had some cramping then I was fine this morning. This afternoon I had cramping again along with the same small amount of brown when I wipe. The dr isn’t worried till she sees red. But I can’t help but worry.. anyone else experience this at 5 weeks and a few days? Sorry if the pic is TMI!!
