Light brown/tan discharge

Stephanie • 28. TTC baby number two!
Hi ladies, 
I am exactly 6 weeks today and have had bouts of tan to light brown discharge... I have had clear to white discharge more than normal since finding out I was pregnant but today is the first day it was not clear. I have also had constant cramps only on my left side, very similar to ovulation cramping. Kind of worried, as my last pregnancy I started spotting around 6 1/2 weeks and ultimately miscarried around 8 1/2 weeks! Any advice or piece of mind? My first appointment is a week from today. Hope everyone else is doing well!
