Continuous Brown Discharge

Has anyone had continuous brown discharge during pregnancy? I noticed the discharge at 6 weeks 6 days of pregnancy. I was checked at 7 weeks and my little peanut had a heartbeat! However, the discharge is still there but only when I wipe. I'm 8 weeks pregnant today. My first prenatal appointment is tomorrow. I'm trying to remain positive that my baby is still alive and well, but this brown stuff is absolutely driving me crazy.
