If you get a positive test result on the first day of your missed period, it's probably about 2 weeks since you conceived. You can use the pregnancy due date calculator to work out when your baby is due. More sensitive tests may be able to confirm that you're pregnant from as early as around 8 days after conception.

Typically the instructions will tell you that the window of opportunity to read the test is about five minutes long. After this point, the test may continue working and it may look like a faint positive when in fact no hCG was detected in your urine.

Chemical pregnancy The most common explanation for a "false positive" is that you really were pregnant when you took the test. "Some women can get a positive pregnancy test and then three days after their period is due, they have a really heavy period," says Lanalee Araba Sam, M.D., an ob-gyn in Fort Lauderdale.

False negative results (test is negative, but you are actually pregnant) usually occur if the blood pregnancy test was performed too early (a rule of thumb is that it takes at least 7 days after conception for the test to show a positive result).

A line on a pregnancy test may show a positive result if: There is visible dye in the line, even if the color is faint. The line appears within the period specified on the instructions, which is usually 3–5 minutes. A woman has taken an early-result test at least 11 days after ovulation.

How long to wait to do a pregnancy test? While these home pregnancy tests can test positive for pregnancy as early as ten days after conception, obstetricians still suggest you wait until the first day of your missed period. This is the time when the hCG levels will be high enough to test on every home pregnancy test.

For pregnancy, earliest test to confirm is serum pregnancy test, positive 4–5 days after a missed period. Ultrasound can show gestational sac at 4.3–5.0 weeks (a sign of pregnancy). But cardiac activity (a sign of life) only begins at about 6 weeks.

Although you may start to feel early pregnancy symptoms before your period, most women have to wait for an average of two weeks from the time they ovulate for a positive home pregnancy test result. Home pregnancy tests measure levels of human chorionic gonadotropin (hCG).

Your body begins to produce HCG after you conceive. If you get a positive test result on the first day of your missed period, it's probably about 2 weeks since you conceived.

Around eight days after ovulation, trace levels of hCG can be detected from an early pregnancy. That means a woman could get positive results several days before she expects her period to start.

These days, certain urine tests are highly sensitive and can detect very low levels of beta hCG, the hormone produced by a developing pregnancy. Most doctors recommend waiting until the first day of a missed period or two weeks after ovulation to reliably show a positive pregnancy test.

They're miscalculating when they ovulated. This is most likely the case for anyone who claims to get a positive test at 7 DPO or earlier. It can take up to two days for hCG to build up to detectable levels, but it can happen sooner for some women. This could explain positive pregnancy tests as early as 8 – 10 DPO.

As soon as the fertilized egg implants into the uterine wall, the hCG pregnancy hormone is produced. This means a high-quality pregnancy test could detect a pregnancy in as little as 5 days after conception.
