Nowadays, you can completely apply home pregnancy test methods without having to go to the clinic or hospital. However, these methods can give different results, even false positives. This depends on the woman's body condition and the quality of the pregnancy test used.
1. What is a home pregnancy test?
Home pregnancy test is a method that can tell if you are pregnant or not. This method will be based on findings of the presence of a hormone called human chorionic gonadotropin (hCG) in your urine.
This hormone is normally produced by the cells that will develop into the placenta. It will initially enter your bloodstream when the fertilized egg begins to implant in the lining of your uterus, as early as 6 days after fertilization. Then, the amount of hCG in your body will increase rapidly over the next few weeks, and often double every two days, or so.
You will be pregnant when the test detects hCG hormone in your urine, that is, the result is positive.

2. When to use pregnancy test to get accurate results?
For accurate pregnancy test results, you should take a pregnancy test about a week after your period is late.
At that time, a woman's body will produce enough hCG to give a positive result. If you get a negative result, you can wait and take the test again while still not getting your period.
3. How to use home pregnancy test?
First, check the expiration date on the pregnancy test product packaging. If the pregnancy test is stored in a humid or high temperature environment, such as a bathroom, it may give false results when tested. So you better throw it away and buy a new pregnancy test.
For best results, you should try testing early in the morning, when your urine is at its most concentrated. Besides, pregnancy test strips can also have different ways of displaying results. Some show pink or blue lines on the test strip, while others show a red plus or minus sign in the cells. So read the user manual.

4. False positive results
False positives are uncommon, but they are still possible under certain circumstances, including:
You have had a miscarriage or abortion within the previous 8 weeks, or you are pregnant (Molar pregnancy) You are already taking certain fertility drugs that contain hCG – used to stimulate ovulation in fertility treatments Have rare health conditions, such as tumors hCG secretion You are using an expired or faulty pregnancy test kit If you get a positive result early, but get your period soon after, there is a high chance you have a chemical pregnancy. This means that the fertilized egg implanted in your uterus and developed just enough to start producing hCG, but then stopped developing for some reason. This type of early miscarriage usually occurs when a fertilized egg has defects that prevent it from developing as it should. After a chemical pregnancy, your period may come out a little more heavily and a few days later than usual.
