Light brown discharge at 6 w1d

I work night shift at the hospital , I am 6 weeks 1 day, I used the bathroom when I got home and when I wiped there was small amount of light brown discharge,no unusual cramping or bright red blood, talked to Ob office and they said it should be ok. Just work up and it's still there when I wipe but very little and none is showing on underwear. Not feeling as bloated today either. I know the Ob said not to worry but I still am. Any thoughts or suggestions?
