How long after can I use the pregnancy test stick

Women who have sex on a regular basis are most worried about unwanted pregnancy. If an unwanted pregnancy requires abortion, it will have a great impact on women's health. Generally speaking, a woman can be diagnosed with pregnancy about ten days after having sex. This can be detected using an early pregnancy test. However, the test strips sometimes have errors. It is best to go to the hospital for a blood test. If the pregnancy is confirmed and is not an unwanted pregnancy, an abortion must be performed as soon as possible.

Best time to test for pregnancy

When can you test for pregnancy? Generally speaking, women can find out whether they are pregnant about a week to 10 days after they actually become pregnant.

Once the male sperm and the female egg combine to form a fertilized egg, about 7-10 days after the fertilized egg implants in the endometrium, the placenta of the pregnant woman will secrete a special substance called human chorionic gonadotropin, which is often referred to as hCG in medicine. It only exists in the body of pregnant women. About a week after pregnancy, human chorionic gonadotropin will appear in the urine of pregnant women, but in the first few days of pregnancy, the secretion of this substance is relatively small and it is not easy to be measured. It is usually more obvious 10-14 days after pregnancy.

Generally speaking, about 18 days after normal sexual life, you can determine whether you are pregnant by testing urine, especially morning urine. The earliest time to detect whether you are pregnant is one week after sexual life, and the latest time is about 3 weeks.

One dark and one light on the early pregnancy test paper may also be caused by external reasons. There are four reasons:

1. If you have just gotten pregnant or have an ectopic pregnancy, such as an ectopic pregnancy, the HCG level in your body is generally low, and the color band in the test area only appears faintly, which will also cause the early pregnancy test paper to have one dark and one light color.

2. In extraordinary cases, such as hydatidiform mole and choriocarcinoma, the HCG level in the body will be too high and the urine test will not show a positive result.

3. After 3 months of pregnancy, HCG levels decrease and urine tests may sometimes show negative or weak positive results.

4. The early pregnancy test paper is too sensitive. During the ovulation period, women's HCG and LH will reach a peak and return to normal levels after ovulation. However, before the next menstruation, these two values ​​will increase a little. If the early pregnancy test paper used is too sensitive, it will easily show a shallow test line. Therefore, if one result on the pregnancy test paper is dark and the other is light, it may be a fraud. It is recommended that you buy another pregnancy test paper after 3 days and test again. If the color gets darker, then congratulations, you have won the prize. Go to the hospital to get your blood tested for HCG official confirmation.
