2 days late and 2 BFN - help?

hi all, just wondering if this has ever happened anyone else? i am now almost 3 days late and done a test yest and it was negative and one the day before also negative. im normally very regular and not particularly stressed out at the minute.

I'm just going to add I'm the same I would love to hear from someone. I'm 2 days late and getting BFN,I have no twinges no mood nothing I'm never late always on the day! Last month I got BFP for about a week then gone,Dr. said it was probably a chemical pregnancy now I'm freaking out that there may be something wrong with me. I really don't know how to feel!
