Should I get my hopes up?

My LMP was Aug 13th and my fiance and I BD'd on Aug 25 and the 27th...a week before AF was due I had some slight spotting for two days...not enough to fill a panty liner but enough to notice...AF was due 2 days ago but hasn't appeared..I have not had any cramping like normal when AF is coming but a weird pulling behind my navel... I have very tender but always hurt right before AF..only other weird thing is that I have really wanted hot and spicy foods like crazy...I did a HPT 2 nights ago but it was a BFN...I am on pins and needles...should I get my hopes up or maybe AF is just late..(she's usually right on time)..any advice would be helpful.
