advice please. :-/

Hi ladies- I was supposed to get AF last Friday, and I'm usually right on schedule. she didn't show so on Sun I took a test, faint line, but no symptoms other than missing AF. Took another test mon morning, still faint line, no symptoms. Yesterday I started to get light pink discharge when I wiped, but still no AF. This morning I took another test and the line is even fainter than it was Tuesday. should I consider this month a lost attempt? thanks ladies, I've been anxious for a week.
