Implantation ?: Have you had unprotected sex? If so this could be implantation bleeding. If your period doesn't come in the next two weeks, check a home pregnancy test.

Pregnancy test later: Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for 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.
