MC 9/16/14 still no AF... Anyone else?

Suffered a MC 9/16/14 and my bleeding lasted 15 days. I've been waiting for AF to show up and still nothing. I used opk's and had a positive surge about 5 days ago. We haven't actively 'tried' but we haven't 'not tried' either. I was told to wait one cycle but I'm getting impatient. I feel like the sooner we can start the better I will feel! Anyone in my situation? Any input will be helpful!
