Hi!
Congratulations!
Spotting after intercourse is quite common, and especially in the setting of a yeast infection. The brownish color suggests that the bleeding slowing down and will hopefully stop soon. I always ask my patients to call me if they have spotting, and will usually do an ultrasound just to double check that everything is fine. In your case, chances are very good that everything is OK -- If you were my patient, I would say 90+%
Good luck!

I also still have spotting this morning. It has turned to brown but it's still there every time I wipe.
I wanted to add that at 6 weeks 1 day my HCG level was over 13,500.
