Expired pregnancy test stick shows two lines

The substances attached to an expired pregnancy test stick may become ineffective. When the substances on the expired pregnancy test stick come into contact with urine, the correct test results will not appear. Therefore, girls must observe the validity period of the pregnancy test stick before using it. If the pregnancy test stick has passed its shelf life, do not use it and just throw it away. Otherwise it will mislead your judgment of the real situation.

1. The pregnancy test stick has two bars after a long time.

If you are pregnant, the chorionic villus test rarely has errors. Contraception will not affect the test results. For early detection, you can go to the hospital for skin exercises. If you are not pregnant, there will be no result after 10 hours, which means you are pregnant. Test again the next day. The flow of goods will be very fast within a month, so it is best to go for a check-up. However, too many miscarriages are not good for your health. It is recommended that you take condoms in the future and take less contraceptives, which are not good for your health. If there are two bars on the pregnancy test stick, you should be pregnant. The lack of clarity may be due to the fact that the test was performed too early. The pregnancy test stick has two lines after a long time.

2. The results of pregnancy test sticks may not be accurate

Pregnancy is a major event in a woman's life, and as for whether or not they are pregnant, I believe most women will use a pregnancy test stick to check themselves first. So, can the pregnancy test stick, an early pregnancy detection tool, be 100% reliable? Liu Yan said that the results of self-testing with a pregnancy test stick can only be used as a reference.

There are many factors that affect the test results of pregnancy test sticks. For example, within 7 days after a woman's ovulation period, when the HCG hormone level in the body is still relatively low, it is easy to detect a false negative using a pregnancy test stick.

It should be noted that when the pregnancy test stick shows "two bars", do not assume that you are pregnant and stop doing further tests. Because "two bars" does not necessarily mean pregnancy. In addition to the human chorionic gonadotropin in urine that can cause two bars to appear on the pregnancy test stick, certain tumor cells or hydatidiform mole in a woman's body may also cause "two bars" to appear on the pregnancy test stick.

3. The accuracy of home pregnancy test sticks

According to the survey, the accuracy of home pregnancy test sticks is as high as 99%, which is almost the same as the accuracy of urine pregnancy tests done in hospitals. Home pregnancy tests are available at most pharmacies and do not require a prescription. One of the benefits of this testing method is that it gives you more privacy and flexibility. You just need to find a bathroom anywhere and spend a few minutes to get the results.
