a little confused but trying to not get my hopes up

Skyler
So I usually spot day 27 and 28 and start my period on day 29. Today is my 28th day and no sign of AF yet. I tested day 26 with a BFN. I don't want to waste my money on another test just to get the same results so Im thinking of waiting it out. 
Any opinions?? 
I don't really have any feels of being pregnant or anything other than my bowels have changed, indigestion and tight muscles in my left leg lol
