My period has been delayed for 9 days and has not come yet

The best age for women to get pregnant is between 25 and 30 years old. Women of the same age who have same sex may wonder if they are pregnant because they find that they have had sex during their menstrual period and cannot take a test. Is it impossible to detect pregnancy 10 days after menstruation? There are several situations in which pregnancy cannot be detected. My period is nine days late but I still can't detect it?

My period is nine days late and I still can't detect it

The value of gonadotropin in the human body one month after pregnancy is a hormone secreted by pregnant women. It exists in urine and blood. Generally, it will appear in urine a few days after pregnancy, but because the amount is small, it is not easy to test it at the beginning. It will not become obvious until 10 to 14 days. Therefore, it is recommended to test 10-14 days after the menstrual period is delayed, and it is best to use the first urine in the morning for testing.

Ovulation occurs on the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it takes 6-7 days for the sperm and egg to combine to produce human chorionic gonadotropin, and the pregnancy test stick is determined by human chorionic gonadotropin. However, human chorionic gonadotropin only begins to be secreted in large quantities after it is embedded in the ovum, at which time the transformed trophoblasts begin to secrete a large amount of human chorionic gonadotropin. As everyone knows, it takes at least 11 days for the egg cell to be implanted for pregnancy.

From this point of view, the most accurate method is to use a pregnancy test stick to detect 7-10 days of delayed menstruation, because the pregnancy test stick mainly determines whether the woman is pregnant by testing the HCG component in the urine of pregnant women. Because the consumption of human chorionic gonadotropin (HCG) varies among women, the test results obtained by testing too early with a pregnancy test paper may not be accurate. When the menstruation is delayed by 7-10 days, the concentration of human chorionic gonadotropin in women's urine is the highest, so the test results obtained are usually the most accurate.

There are several situations where the pregnancy test cannot be detected

Under normal circumstances, pregnancy can be detected 18 days after having sex, or 7-10 days after menstruation. This is because after the sperm and egg fuse into a sperm-egg combination, it takes 6-8 days to embed into the uterine wall, and then the HCG metabolized by the embryo can enter the urine for 7-10 days. In conclusion, it is scientifically proven that pregnancy can be detected from the urine of gay men after 18 days of intercourse. The first 7 days of sexual intercourse are generally about 14 days, and a few days beyond 20 days can be used to detect pregnancy, which can be confirmed by self-test strips or hospital outpatient HCG tests.

If pregnancy cannot be detected, the testing method may be incorrect. After all, ovulation test strips, pregnancy tests, and other self-testing kits aren't 100% accurate. But perhaps, the woman herself is not pregnant, but only due to other symptoms. Therefore, it is best for women to go to the hospital for a definitive diagnosis. Under normal circumstances, the sperm and egg will transfer from the fallopian tubes to the uterus, then stabilize and gradually grow into a fetus. However, due to various reasons, the sperm and egg detour in the process of moving forward and do not reach the uterus, but stay in other places, which becomes an ectopic pregnancy, also known as an ectopic pregnancy.
