TMI (pic) spotting/ discharge

I really hate to do this but I am desperate... I've had two miscarriages before. One was missed at 3 months and the other natural at 5 weeks. I have been having brown discharge for two weeks off and on. Sometimes it's more tan and others it's really dark. Never red or pink yet. My levels are good according to doctor but I havent had an ultrasound yet. I go next Wednesday. I am now 6 weeks. At 5 weeks 3 days my hcg levels were over 14000. Unfortunately I have attached a pic but I am desperate. Please respond if you have had  his or know anything about it! Thank you! ​
