How early can I detect pregnancy?

Many women may be very anxious and want to know whether they are pregnant or not. So they also want to know how long it takes to detect pregnancy. This will help them understand what to prepare during pregnancy and adjust a healthy mentality to welcome their baby.

How long does it take to detect pregnancy?

Before the sperm and egg combine and the embryo implants, there is no contact with the pregnant mother, so we have no way of knowing its existence. After the embryo implants, the surface trophoblast cells where the sperm and egg combine produce a protease that dissolves the uterine wall in contact with it. The fertilized egg is buried in the functional layer of the uterine wall. At this time, the transformed trophoblast cells will grow and extend many cell protrusions, which are uniformly villi, called villi. Therefore, the hormone it secretes has a very strange name ---- hcg gonadotropin (HCG). Now, we can calculate more accurately how many days after AA can we detect the presence of this hormone! After fertilization, the egg takes 4-5 days to travel from the fallopian tubes to the uterus and stays in the uterus for 3-4 days. This process takes a total of 7-9 days. Therefore, if you use a more sensitive (15 standard units) pregnancy test kit, it is very normal and effective to detect HCG about 7 days after ovulation AA; use a regular early pregnancy test strip (25 standard units) about 12 days after ovulation. The phenomenon of one dark and one light on the early pregnancy test paper may also be caused by external reasons. There are 4 reasons: If you are pregnant soon or have an ectopic pregnancy, the body's HCG level is generally slightly low, and the printed color band in the test area only appears vaguely, which can also cause the early pregnancy test paper to have one dark and one light.

In extreme cases, such as hydatidiform mole and choriocarcinoma, the body's HCG level will be too high and the urine test may not show a positive result. After three months of pregnancy, HCG levels decrease and urine tests may sometimes show negative or weak positive results. Early pregnancy test strips are particularly sensitive. During ovulation, women's HCG and LH will reach a peak, and will return to normal levels after ovulation. However, before the next menstruation, these two levels will rise a little. If the commonly used early pregnancy test paper is particularly sensitive, it is easy to show a faint test line.

What is ectopic pregnancy?

What are ectopic pregnancies? Ectopic pregnancy, also known as ectopic pregnancy, refers to the abnormal pregnancy process in which the fertilized egg implants and develops outside the uterus, with fallopian tube pregnancy being the most common. It is often caused by inflammation of the fallopian tube lumen or its surrounding area, which leads to poor lumen smoothness, blocking the normal movement of the fertilized eggs, causing them to be retained in the fallopian tubes, embryo implantation, and development, resulting in miscarriage or tubal rupture. There are usually no obvious symptoms before miscarriage or rupture, but there may also be symptoms of amenorrhea, abdominal pain, and a small amount of vaginal bleeding.

Once ruptured, the symptoms include acute severe abdominal pain, recurrent attacks, vaginal bleeding, and even shock. However, obese women cannot be diagnosed by a variety of tests, which can easily delay treatment and cause serious consequences. If you are not considering becoming a mother yet, you need to take good contraceptive measures. Good contraceptive measures can prevent the occurrence of ectopic pregnancy from the source. At the same time, pay attention to timely treatment of urinary system diseases, pay attention to hygiene during menstruation, delivery and confinement period, and avoid urinary system infections. Go to the hospital for examination as soon as possible after menopause to confirm the location of pregnancy. For obese women, it is recommended to control their weight within an effective range before pregnancy.
