cramping for few days but no period

I'm late 5 days on my period and no signs of it!! I took tests and both were negative. I have cramping but no signs of AF. I'm praying it comes because I'm getting married in 2 months and was going to TTC then. I have a VERY normal cycle and now nothing. I'm worried because if I'm not, what could of caused my lateness?? Anyone on time with their cycle and was late by almost a week?!? My cycle below.
