Spotting

So I’m 6 weeks & 6 days. I’ve been spotting for a week and a half. I went to get ultrasound 2 days ago and everything was perfect. But I hate seeing the spotting. Sometimes it’s more than other times. Always brown. & tends to be more if ive been up walking around. Has anyone else been through this? Thoughts? Opinions?

Dr. Said it was normal but like it said at times it’s more than other times. Doesn’t seem like it’s stopping. Occasional cramping nothing too bad.
