Brown spotting!

Alyssa • 🌻
Has anyone had off and on brown spotting? 
I'm 6 weeks 5 days and it's been going on 2 days! My OB says its normal as long as it's not bright red and filling a pad and no cramps, which it's not. It's really only when I wipe. It's here one minute gone the next! Just seeing if anyone has experienced anything similar to this?
