How many days after sex can I use a test strip to detect pregnancy

Nowadays, the pressure of life is relatively high. It is difficult for many people to get pregnant because they are also emotionally anxious. In addition, due to the opening of the second-child policy, many older women also want to have a second child, but because of their age, pregnancy is not so easy. So how can they know that they are pregnant as soon as possible? In other words, how many days after intercourse can one detect pregnancy using a pregnancy test?

How many days after intercourse can I use a pregnancy test to detect pregnancy

The sperm and egg combine before the embryo implants and has 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, forming a uniform villus shape, which is called villi. Therefore, the growth hormone it secretes 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, it is very normal and effective to measure HCG about 7 days after ovulation; or use a regular early pregnancy test strip (25 international units) about 12 days after ovulation.

Generally speaking, women can test whether they are pregnant about a week to 10 days after they actually become pregnant.

It is understandable that you want to get pregnant in a hurry, but you should not be too anxious and worried, because excessive anxiety will make it more difficult to get pregnant successfully. It would be best if both parties could release their stress and mental state and look at the matter with a good attitude. If conditions permit, each other can go on vacation to other places, see the beautiful mountains and rivers of our motherland, and perhaps there will be good news when you return home.
