Pregnancy test paper pregnancy picture

Many women, once they find that their menstruation is delayed, or if they are planning to get pregnant and want to know whether they are pregnant as soon as possible, will go to the pharmacy to buy pregnancy test paper in advance. Pregnancy test strips are not only very convenient and easy to use, they can give you quick results, and the results are generally quite accurate. So which pregnancy test papers indicate pregnancy?

Pregnancy test paper is a way to determine whether a woman is pregnant in daily life. Its basic principle is to determine whether a woman is pregnant by testing the concentration of hcg in urine. HCG is a special hormone secreted by women during pregnancy. Because it is a glycoprotein produced by the embryo, it is excreted in the urine through the renal tubules and can be detected through pregnancy test paper.

When checking the pregnancy test paper, if there are two dark purple lines on the pregnancy test card, that is, both T and C show red, it means that hcg in the urine is positive, indicating pregnancy. If there is only a dark purple line on the test paper, and purple appears in the C position, it means that the hcg in the urine is negative, which means that you are not pregnant.

If there is no dark purple line on the pregnancy test paper, it may be that the test was not performed properly or there is a problem with the early pregnancy test paper, and it is necessary to check again. Regardless of the test results, it is recommended to test again two to three days later to ensure the accuracy of the results. If it is confirmed that you are pregnant, you can go to the hospital for a final diagnosis.

How long after sex can I test for pregnancy

The most important issue for couples who want to have children is how long it will take to test for pregnancy after having sex. Many women want to use pregnancy test sticks to detect whether they are pregnant. At this time, they need to first understand the answer to the question of how long after having sex to test for pregnancy, so that they can have a rough idea.

1. Generally, a test strip can be used 15 days after the couple has sex, and a blood test for HCG can be done a week later to confirm whether the pregnancy is confirmed.

2. The ovulation period is around the 14th day of the menstrual cycle. If fertilization is successful at this time, it will take 6 to 7 days for the combination of sperm and egg to produce HCG. The pregnancy test sticks are all determined by testing urine HCG. HCG actually starts to secrete in large quantities after the fertilized egg implants, and the transformed trophoblasts begin to secrete and produce HCG in large quantities. It takes at least 11 days for the fertilized egg and embryo to implant. Therefore, for the first 6 days, if you want to be more precise, wait until 11 days, then it will be more accurate.

3. Using a pregnancy test stick can simply and relatively accurately test whether a woman is pregnant, so it is very effective for female friends to know when to use the pregnancy test stick most accurately. However, pregnancy test sticks are not very accurate, so if you want to know for sure whether you are pregnant, it is better to go to the hospital for a check-up.

4. It is recommended to use the first urine in the morning for testing, because female hormones are easiest to detect at this time. If used at night, the urine must be allowed to remain in the bladder for at least four hours before it can be detected. Also, don't drink too much water in an effort to increase your urine volume, as this will dilute your growth hormone levels.
