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.
There are several vegan-friendly options for pregnancy tests, such as the First Response Early Result Pregnancy Test and the Clearblue Digital Pregnancy Test. These tests do not contain any animal-derived ingredients and are not tested on animals.
The rabbit test, used for pregnancy detection, was replaced in the 1960s by more reliable medical tests like urine-based pregnancy tests and later blood tests. This change happened due to ethical concerns and advancements in scientific technology.
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.

Cortisone would not typically affect the results of a pregnancy test. Pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in urine or blood, which is a hormone produced by the placenta during pregnancy. Cortisone would not interfere with this hormone or affect its detection in a pregnancy test.
"For the most reliable results, it's ideal to take a pregnancy test after you've missed your period, but some tests can potentially detect pregnancy as early as 10 days after conception. Waiting until after missing a period is preferred for a more accurate result. Here's a general guide: Early detection tests may detect pregnancy 6 days before you miss a period, although results are more reliable closer to or after missing a period. The highest accuracy (over 99%) is obtained when you test on or after the day of missing a period. For best results, test in the morning, when hCG (the hormone of pregnancy) is most concentrated in your urine. For more information, you can visit Benecare Maternity Hospital."
No, Red Bull or similar energy drinks do not cause false positives on pregnancy tests. Pregnancy tests detect the hormone human chorionic gonadotropin (hCG), which is specific to pregnancy. While certain medications or medical conditions can affect test results, the ingredients in Red Bull, such as caffeine and sugar, do not interfere with hCG detection.
