Most tests these days will detect the hormone in 9 to 10 days.
Home pregnancy tests can detect the HCG pregnancy hormone as soon as your first missed period. Doctors can detect the HCG hormone as early as 9 days past ovulation with blood work. It is usually safe for couples to share the news of their pregnancy with family and friends after the end of the first trimester, or 12 weeks gestation.
Only thing that can tell you that is a pregnancy test! GOOD LUCKHome pregnancy tests can detect the HCG pregnancy hormone as soon as your first missed period.

This will generally depend on the test that is used to detect a pregnancy. Blood tests are more accurate in that they can detect a pregnancy earlier. As soon as two weeks after a missed period, blood tests can detect levels of Hcg (the hormone pregnant females produce). Urine pregnancy tests generally do not detect a pregnancy before the 6th week because sometimes it takes that long for Hcg levels to rise to the point where a urine test will be sensitive enough to detect it.
A pregnancy test can be positive before you even have missed a period. Many tests can provide positive results within 10 days after you become pregnant, however it is usually best to wait until you've missed a period because the HCG hormone (the hormone found in early pregnancy)will be stronger which in that case will give you definite results.
OBGYNs typically don't do pregnancy tests until your period is 2 weeks late. This is because many pregnancies do not last past the 1st week or so, and OBGYNs treat viable pregnancies. Before the availability of home pregnancy tests, most women did not know they had an early miscarriage. With home pregnancy tests, you can test as soon as it is time for your period. This is because once the egg is fertilized and implants into the uterine lining, there is a new hormone released. The pregnancy test shows if that hormone is present. Without that hormone being present, the uterine lining sheds and you have your period. Thus, you can know you are pregnant as soon as you expect your period.
Yes, you can still be pregnant with a negative reading on a pregnancy test. Factors include incorrect usage of an at-home test, taking the test soon after conception (before the pregnancy hormone has a chance to "register"), and certain drugs used while taking the test that alter the pregnancy hormone. If you are unsure about the results of a pregnancy test wait a few days and take the test again or go to your ob/gyn for a blood test.
There aren't many false positive pregnancy tests.The test is looking for (HCG) Human chorionic gonadotropin which is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception.Since the hormone is made by the embryo it is had to have a positive test from a woman who is not pregnant.
Some of today's early pregnancy tests can test as soon as 10 days after ovulation (which is usually around the same day that you had sex, it could possibly be 2-3 after sex but never before). The safest bet is to wait 19 days after having sex. If you still test negative, you are probably not pregnant.
