If you do not chart or monitor your fertility in any way, and you think you may have conceived, you should wait 19 days (or longer) after having sex to test. Why 19?! Sperm can live approximately 5 days in the proper environment; if the sperm managed to live until you popped an egg, the actual conception could have taken place several days after the sex act that got the sperm there. To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then. Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.)

A blood test however will show your pregnant 7 days following conception.

as early as 3 days before your missed period. You cant just take it after sex because say at that time you did get pregnant, nothing really happens yet. So for example if you are suppost to get your period on February 17th, You could take it about February 14th and still get an accurate result, but the longer you wait, the more accurate. Good luck.

for it to be 100% accurate you should wait until the day after you miss your period (so for most people thats around 2 to 3 weeks)and take the test, if still negative see a doctor in a few days.

Pregnancy tests are so sensitive that they can detect it 24/48 hours before the day your period should come. So its not when you have sex, its the date of your period that you should take into account for the test.

You might want to wait to see if you get your period first. Although there are tests that you can take as early as a few days before your period is due. Good luck!

depends on where you are in your cycle......
And if you are having unprotected sex, you definitely should be keeping up with your cycle.
