Brown-ish discharge in underwear

Ladies. What do you think? I am 9w 2d and have had a previous missed miscarriage. I just went to the bathroom and have some discolored discharge (sorry for tmi) in my underwear but when I use the restroom and wipe it's all clear. I also shoved a little TP inside to verify it was clear discharge now. Should I give the doctor a call or have some of you had an issue like this.
