Femometer Early Pregnancy Test has a sensitivity to the pregnancy hormone hCG at 12.5 mIU/ml. You can test with Femometer Early Pregnancy Test from 9 days after fertilization/5 days before expected menstruation.
We recommend testing with morning urine if you want to use an early pregnancy test before your expected menstruation, as the level of hCG is highest in concentrated urine in the morning.
Pregnancy tests today are of such high quality that they are more than 99% accurate from the day of expected menstruation. The same applies to the Pregnancy Time Early Pregnancy Test Stick.
When using an early pregnancy test and testing before the expected menstruation, the accuracy is lower. Clinical tests on most early tests, for example, show that about 70% of pregnant women will get a positive result on an early pregnancy test 4 days before the expected menstruation. This means that you can still be pregnant even if you test negative with an early pregnancy test before your expected menstruation.
If you test early, you may also risk detecting a biochemical pregnancy, which is a pregnancy that ends within the first few days after fertilization. In this case, you may get a faint positive pregnancy test result that becomes less noticeable over the following days, possibly turning completely negative on the day of expected menstruation.
Yes, it is because some women are very quick to produce hCG, while others may take more time.
There can be a significant variation in the time it takes for a fertilized egg to reach the uterine cavity and implant itself. It is normal for this process to take anywhere from one day to one week. However, since the production of the pregnancy hormone hCG begins approximately 9 days after fertilization when the egg implants in the uterus, some women can have a positive pregnancy test one week before the expected menstruation, while others may not have a positive test until a few days after the expected menstruation.
If you receive a negative result on an early pregnancy test, it can be a good idea to test again later.
The accuracy of early and regular pregnancy tests is currently so high that it is extremely rare for a false positive result to occur. If your test is positive - meaning if a colored line appears on the test line of the pregnancy test within the specified time frame - then you are pregnant.
However, some individuals may still experience menstruation on the expected date or a few days later, leading them to believe that the pregnancy test was a false positive. In most cases, this is due to a biochemical pregnancy loss - meaning a fertilized egg that did not successfully implant in the early stages of pregnancy. However, it does not change the fact that if a colored line appears within the specified time frame stated in the instructions, it indicates an elevated hCG level, which means that you are - or were - pregnant.
Note that there are medications that can cause an increase in hCG levels without being pregnant.
The pregnancy hormone hCG rises rapidly if you become pregnant. That's why pregnancy tests are designed to react to an elevated hCG level, which indicates that you are pregnant.
Pregnancy tests have two antibody lines. One is the control line, which will show color when dipped in urine. If the control line appears with color, it confirms that your test is functioning properly. The other line is called the test line, and this line will only show color if your urine contains the amount of hCG that corresponds to the sensitivity of your pregnancy test.
The most sensitive early pregnancy tests can yield positive results when your hCG level has risen above 5 mlIU/ml.
