Some of the most sensitive tests can begin detecting the HCG hormone at levels as low as 6, or 6-7 days before your period is due.
The early detection tests say 5 days before a missed period. I personally have been able to test positive as early as 9 days past ovulation.
Most of blod and urine pregnancy tests measure the level of hormone called hCG, which is created after the egg is fertilized. Different pregnancy test may have different sensitivity, so it will depend on particular test type when it will test positive. However usually a pregnancy test will test positive after first few days of pregnancy.
Some tests can show positive before your period is even late. It depends on how sensitive the test is. If using an early detection test with negative results, retest when your period is a week late. The test looks for hCG, a hormone that can vary greatly from woman to woman and pregnancy to pregnancy.
Pregnancy tests, especially early-stage home tests, are never 100% reliable.
Yes it can if you have tested too early. Here is a link for information on how pregnancy tests work: http://thefertilityshop.com/fertility/pregnancy-tests-work-a-17.html
Yes. Home pregnancy tests actually give accurate results in the first trimester, some as early as the first few weeks of pregnancy.

The home pregnancy tests only look for the hormones released by being pregnant. As it takes a while for hormone levels to raise to a suficient level for detection, this might be undetectable in the very early part of your pregnancy. As pregnancy carries on, this will most always show up after 4 to 6 weeks. If you are unsure, then you might want to have a "professional" test done at a clinic.
An ovulation predictor kit is used to help women keep track of ovulation when they are trying to conceive. Pregnancy tests are designed to predict a special hormone in the body that pregnant women have. Since an ovulation kit is not designed to detect that pregnancy hormone, it cannot be used as an early pregnancy test or any other type of pregnancy test for that matter. OPK's and pregnancy test are not designed alike, and are not meant for the same purpose.
Some pregnancy tests can detect pregnancy as early as when a woman is two days late with her menstrual cycle. You will only know the outcome if you take the test.
Some early signs of pregnancy are: feeling bloated, nausea, vomitting, increased hunger, etc. If you have missed your period, and think you may be pregnant get a home pregnancy test there are several for early detection. Also, please don't have an abortion many people would love your baby.
5 days before your missed period i think. that's not with all pregnancy tests tho.
