13-2-2009 - Chemical pregnancy?

My mood while writing this blog: Fine

Has anyone ever experienced a chemical pregnancy? I believe I had one, but not too sure. Here are the reasons why I may of had one:

-I took a few pregnancy tests before my period was due and I got the faintest line ever. but still a line..it was not an evaporation line either.

-My period was one day late arriving on 1.31.09 and I had bad cramps to the point where I had to take something. (I never have to take anything.) I took Advil twice that day

-My period was fairly light after the first day and last 4 days. (normally it would last 5 or 6 days.)

-The fourth day of my period (the day it ended) it was really dark brown (which is noramal) that lasted till Sunday (2.8.09). Then Monday morning my discharge was a tan color (which again, I find normal). Monday afternoon I noticed my discharge was a very very dark brown color w/ some blood in it?! NOW, that was not normal for me at all. Monday-Wednesday my discharge was very dark but no blood besides on Monday. FINALLY on Thursday my discharge was lightening up and NOW today (2.13.09) is it back to a normal color:)

-I'm thinking it was old blood...but it lasted 8 days after my period ended? is that normal?

-Any suggestions would be nice, thanks!
