Late period, usually very regular

Bryanna

So I am 3 days late and I am very regular. For the past 6 months I have gotten my period on the date predicted every month. Sooooo...I have taken a few tests and all negative. I do feel a little bit crampy today but still no period. Has anyone gotten BFN this early on and ended up actually being pregnant? Were you crampy around the time that you would have expected your period? Any comments would be much appreciated! Thank you
