Can pregnancy test paper detect 14 days

During the pregnancy preparation period, many couples want to get pregnant as soon as possible, so that they can be a little more relaxed. Because to be honest, there are many common problems during the pregnancy preparation period, and they have to pay attention to many details all the time, which is also quite tiring. Therefore, many women will use early pregnancy test strips to test 14 days after having sex, but they don’t know whether they can be tested if they are pregnant. So, can the pregnancy test paper detect the result 14 days after intercourse? Let me give you a detailed introduction today.

Can I get a pregnancy test 14 days after having sex?

Generally speaking, women can test whether they are pregnant about a week to 10 days after they are actually pregnant. Once the man's sperm and the woman's egg cell combine to form sperm and egg, the sperm and egg combine to implant in the uterine wall about 7-10 days after the embryo, the pregnant woman's embryo will secrete a special substance called human hCG gonadotropin, which is often referred to as hCG in medicine. It only exists in the pregnant woman's body. About a week after pregnancy, human hCG gonadotropin will appear in the pregnant woman's urine, but in the first few days of pregnancy, the excretion of this substance is relatively small and it is not easy to be detected. It is usually more obvious 10-14 days after pregnancy.

The principle of using early pregnancy test strips to detect early pregnancy is to test the hCG value, that is, the value of hCG gonadotropin in the body. This type of growth hormone is produced by the embryo and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it becomes increasingly obvious after 10-14 months. We need to note that although most pregnancy test tools can detect pregnancy one day after the normal menstrual period, the hCG hormone content in the body of pregnant women varies from person to person. Testing with test strips too early may be inaccurate, so under normal circumstances, it is necessary to test again after a week.

The entire process of sperm-egg combination, from fertilization to embryo implantation, is basically silent, except that a few pregnant women may experience physiological implantation bleeding and slight muscle cramps. If your breasts feel tender, soft, and swollen, you may be pregnant. This type of symptom may appear in the first few days after pregnancy. If your areola darkens, or if there are dark blue and light pink outlines on your breasts, it's probably not your imagination. These are all symptoms of pregnancy. Are you, who have always been full of energy, suddenly feeling exhausted physically and mentally?

A lot of metabolism of luteinizing hormone (a male hormone) can make you feel exhausted.

Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicions. Eight days after ovulation and implantation, you may develop light pink or dark brown stains, and cramps may accompany these conditions. In fact, during the menstrual period, there may be some spotting and bleeding, but this is not a true menstrual period. It is the result of the fusion of sperm and egg and the implantation of the embryo in the uterine wall.

Can I get pregnant with an early pregnancy test after 14 days of intercourse?

It takes 1-3 days for sperm and egg to fuse after intercourse. After the successful fusion of sperm and egg, the sperm and egg will grow and develop while moving through the fallopian tubes toward the uterus, and it will take about 3-4 days to reach the uterus. After the sperm and egg combine and enter the uterus, it takes 2-3 days to find a fulcrum in the uterus for the embryo to implant. After the embryo implants, the sperm and egg combine to connect with the embryo and the uterus. The embryo will produce HCG. HCG will appear in the urine, but the concentration is very low at the beginning. Sometimes the early pregnancy test paper will not show it, or it will always show two lines, one dark and one light.

Because each woman's physical condition is different, some people can find out they are pregnant a week after having sex, while others may not find out until more than 40 days after having sex. Therefore, if the pregnancy test paper does not show results 14 days after intercourse, it is recommended to use the early pregnancy test paper to test one week after the menstruation is delayed. The accuracy of early pregnancy test strips is not very high. The effect of testing too early or too late is not very good. If you have to do a urine test, the negative reaction shown may be incorrect. The early pregnancy test strips mainly test the HCG value in urine to determine whether you are pregnant. In fact, HCG first appears in the blood and then in the urine. Therefore, female friends can go to the hospital for a blood test for pregnancy 10 days after having sex, and the result will be more accurate.
