AF is MIA .

I had light pinkish brown that I could see in the tp when I wiped (sorry for the tmi) for a couple of days on and off. The only reason I noticed, is because I was waiting and looking for any sign of AF. I'm over a week overdue for AF and have had no pinky brown tp staining for a couple of days. Seriously, the pinky brown wasn't even enough to call spotting. A couple of days ago I took a Clearblue pregnancy test and it was negative...I kept thinking I saw a faint line, but I think it was just hopeful thinking.
I made a doctor's appointment for next week to talk about what is going on. I've never had this happen before ever...I always have a very regular, very heavy cycle and my last AF was perfectly normal.
All I know, is that I have every pregnancy symptom in the book and my nausea is getting worse.
Advice, experiences, ideas anyone?
