Bleeding post op

I had my surgery 7/9 and I only had a little spotting here and there up until this last week. I’ve had brown blood enough for a panty liner everyday for about 8 days now. Is this normal? I see posts about brown blood at 3 weeks but couldn’t find anything about how long the blood lasts. It doesn’t smell bad or anything but I also don’t have a strong sense of smell. I’m having a little pain this week but I think it’s because I returned to the office last week too. It’s an office job with an hour commute each way.
