If you want to know whether you are pregnant, the most convenient way is to use a pregnancy test. So, after pregnancy, when is the fastest way to test it out? Let's take a look.

How many days can pregnancy be detected?

The first part introduces the whole process of pregnancy in detail, which is the general situation. For most people, it takes about 10-12 days from fertilization to embryo implantation to detection of early pregnancy test paper, but there are special cases for some people. On the mother's website, some mothers, when showing off their pregnancy results, said that they could test the results in 7 days. This is also possible from the perspective of scientific research.

Mama.com netizen "Meiya520": The last time was on the 23rd, the ovulation period was on the 12th, the strong positive on the 13th, and today on the 20th, the test showed that the desire was gray! I can't believe it,

Mama.com user "syzf9130": Today is the seventh day after my ovulation. I took a test this morning out of curiosity and it showed two marks. The second one is very light pink but still visible.

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 growth hormone it metabolizes has a very strange name-human chorionic gonadotropin (HCG). Now, we can more accurately calculate how many days after AA we can detect the presence of this growth hormone!

After fertilization, the egg takes 4-5 days to travel from the fallopian tube 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 international units) early pregnancy test kit and measure HCG about 7 days after ovulation; or use a regular early pregnancy test strip (25 international units) about 12 days after ovulation, it is very normal and effective.
