False negative

katie
I was wondering if anyone has ever taken a home pregnancy test which came out negative, but later found out they are pregnant.. (Initially has a false negative result).
My period is nearly two weeks late. I took a pregnancy test yesterday which was negative. 
I know it still can be too early to test, or I just may not be pregnant, but I was just wondering if anyone has experienced a false negative before, just to determine how common it is.
