Day 8 of light brown when I wipe

Anyone go through this? I don’t think it’s miscarriage related as it happens when I’m on my feet / really active and a miscarriage wouldn’t care if you’re laying down. Yesterday we had a lazy day (couch and movies) and didn’t see it at all. Today didn’t see it, went to the mall walked a lot and had some when I got back.

My hcg levels are rising accordingly, at 6 weeks they were 17,161 (I’m 6+2 now)

Midwife does not seem concerned she said she considers that discharge and not spotting.

It’s mostly this color sometimes I’ll get a dark string of ewcm (maybe 3 occorunces in the last 8 days so not a lot)

Ultrasound is in 4 days so maybe will have a more peace of mind after I see heartbeat but this is annoying !!!

Edit to add the heaviest it was one of these 8 days:

Ranges between very light though
