Spotting since week 6 of pregnancy advice/prayers.

Has anyone had only brown spotting off and on for a week or so? It started on week 6 and today I’m 7 weeks and it came back yesterday. I am going to a emergency ultrasound today at 2:15 but I’m very worried... I guess I just need prayers or reassurance that some times spotting is normal. It’s only been light brown and only when I wipe. This is our 3rd pregnancy and I’ve never had any spotting during pregnancy before.
