Confused

Ok, so on Nov 18th I got a bfp. I took tests every 2 days after that. Well, on the 28th I had some brown spotting and a bit of light pink bleeding, never enough to fill a pad. The spotting continued for 3 days after that. After the spotting stopped I took a test and it was faintly positive and a couple days later as negative as can be. However I still have every single symptom I had before the spotting began. I went to my first ob appt last Tues just after the dr left for an emergency and they are supposed to call me next week to reschedule. I'm so confused and don't know what to think. Anyone ever have this happen to them and what was the outcome?
