Can pregnancy be detected at 29 days?

If a woman goes to the hospital to check whether she is pregnant, she usually has to undergo a blood test. The blood test is mainly to detect whether the hormone content in the woman's blood has increased significantly. If the hormone content has increased significantly, it indicates that the woman is pregnant. However, there are actually other ways to detect pregnancy, such as early pregnancy test strips. However, it is usually not detectable in the early stages of pregnancy, so can it be detected at 29 days of pregnancy?

Can pregnancy be detected at 29 days?

Pregnancy can be detected at 29 days. About 10 days after intercourse, blood HCG can be checked to determine whether you are pregnant. The early pregnancy test strip mainly detects the HCG hormone in the urine. Generally, the syncytial trophoblast will secrete an increase in the HCG hormone in the urine 6 days after conception. Therefore, if you have regular menstruation, it is recommended to test at least 7 days after the menstruation has obviously stopped to confirm pregnancy.

Human chorionic gonadotropin (hCG) is a glycoprotein secreted by trophoblast cells of the placenta and is composed of two subunits, a- and b-. hCG enters the maternal blood after fertilization and proliferates rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains stable.

In the case of an ectopic pregnancy, the pregnant woman will often feel a heavy pain in the lower abdomen, so painful that she cannot straighten her back, and there will be irregular bleeding with a small amount of brown blood. If the bleeding is heavy and bright red, it means the fallopian tube has ruptured, but it is mostly internal bleeding and rarely will it flow out of the vagina. When the fallopian tube ruptures, there will be severe abdominal pain and shock. If not treated in time, it will be life-threatening.

Ejaculation outside the vagina or if he does not penetrate but just rubs against the vagina outside, there is also a chance of getting the pregnant woman pregnant because the fluid he secretes already contains a small amount of sperm. In addition, if a pregnant woman has sex before her menstruation is completely over, she may suffer from serious gynecological diseases or become allergic to semen, causing infertility.

What are the precautions for early pregnancy test

1. Morning urine. Things to note when doing early pregnancy tests: 1. Use morning urine: Early pregnancy tests generally only require urine testing. When the fertilized egg is implanted in the uterus, a new human chorionic gonadotropin is produced in the pregnant woman's body, which helps maintain pregnancy. This hormone can be detected in urine about 10 days after conception. Urine pregnancy test: When checking for early pregnancy, be sure to use morning urine, because morning urine is concentrated and has higher hormone levels. In order to increase the positive rate of early pregnancy tests, you should try to reduce your water intake the night before.

2. Container. Precautions for early pregnancy test: It is best to get containers from the hospital laboratory in advance for early pregnancy test: because they contain preservatives, urine is not easy to deteriorate. If conditions permit, any wide-mouth bottle can be used, but it needs to be washed and boiled for sterilization or rinsed with boiling water. After collecting about 10 ml of morning urine, send it to the hospital immediately for early pregnancy testing. If the time is delayed too long, it may affect the accuracy of the test. This should be paid more attention to in the summer.

3. Time. Precautions for early pregnancy tests: 3. Pay attention to the time of B-type ultrasound examination: Using B-ultrasound to diagnose early pregnancy is the most accurate and reliable method of early pregnancy examination. As early as the 5th week of pregnancy, which is one week after the menstrual period, a round halo in the uterus, also known as the pregnancy ring, can be seen on the B-type ultrasound screen. The dark area inside the ring is amniotic fluid, in which a rhythmic fetal heartbeat can also be seen.
