Last period was 2 days early and only lasted 2 days (barely) and this period is 1 day late. how long should i wait to take a test?

HPT: You can take a home pregnancy test as soon as you are late for your period. If negative and still no period, consider retesting in one week with an early morning void.

See below: 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.
