Brown discharge 10 weeks

So I’ve been having this discharge since yesterday afternoon. It’s not heavy it’s more like I notice when I use the washroom. It bothers me but I have no cramping and I was going to go to a walk in but I know all they can do is book an ultrasound for most likely a week from now and the tech is closed on the weekend. I also don’t want to go to hospital if it’s not heavy. It has not turned red and no clots or pain😩 I just don’t know what to do
