Pregnancy Test

I'm 6 days late from getting my period, I'm never this late sometimes a day or two. I have symptoms that I'm getting my period but nothing so far, I did take a pregnancy test yesterday and it was negative, my question is has this happened to anyone else and then they ended up being pregnant? Thanks for the input ladies!
