Maybe nothing. Or maybe you have had a very early miscarriage that the home test was not sensitive enough to detect. If you don't want to be pregnant use protection. If you do want to be pregnant wait for the next cycle and see what happens.

Too early. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
