A lot of women eagerly wait to get pregnant and while waiting to see if they are pregnant, they become anxious and inpatient. If a woman takes a pregnancy test too early, the chances that if will be negative are higher even if a woman has conceived.
How pregnancy tests work?
Pregnancy tests are made to reveal hormone that is occurring during pregnancy and that is called human chroionic gonadotropin or hCG in the urine. The tests react to this hormone and few of the tests can even reveal one version of hCG called hyperglycosylated hCG. HCG is secreted if a fertilized egg is attached and embed in the uterus and H-hCG is secreted before this. H-hCG is present in the body right after a woman becomes pregnant and only a few pregnancy tests can detect the presence of H-hCG. These tests that can detect this hormone can reveal if you are pregnant earlier.
Pregnancy tests that can detect pregnancy early
Tests like these accept that luteal phase lasts for two weeks. However, this phase may last longer for some women and they need more time in order to see if they are pregnant. Manufacturers of these tests claim that they are 99% accurate, but the studies show different results. The accuracy of these tests in the studies varies from 46% - 89%. One research showed that these tests detected pregnancy in 80% of pregnant women on the 28th day of their cycle.
When is your period is late and when to take pregnancy tests?
If two days passed after your longest luteal phase and you still don't get your period, then your period is definitely late. When you are not careful about how long your menstrual cycle lasts, you can't know that your period is late. Some of the women experience menstrual cycle irregularities. Studies showed that of 100 of these women, 10 to 20 of them will get negative results even if they conceived. If you take pregnancy tests early, you could get a false negative result and get frustrated because of that. You will also spend your money for getting wrong information. You should take the test if your menstruation is late, and by doing that you will avoid getting the wrong results. Those women who have irregular periods should take the test after the time of their longest cycle passes, which means that if you get your period on the 30th to 35th day of your cycle, then the best time to take the test is on your 36th day of the cycle..
