Can I test for pregnancy one week after having sex?

Women always have so many doubts and worries about pregnancy. Some pregnancy symptoms are obvious and you can tell soon after the pregnancy. But for some people, pregnancy symptoms are not obvious. How do you know if you are pregnant? How many days during pregnancy can the test be detected?

The whole process of pregnancy

If you want to know how many days it will take to detect pregnancy, you must first understand the entire process of pregnancy.

4~6 days after fertilization, the sperm and egg have not yet taken root and settled. It floats and swims in the uterus, absorbing sufficient nutrients and then disintegrating until it becomes a complete and cell-forming embryo. Starting on the 7th day, healthy embryonic cells grow a tail-like drill to drill into the mother's uterine lining, and then develop into the fetal umbilical cord connected to the mother.

On the 7th to 10th day, the embryo finds a suitable and comfortable position on the inner wall of the uterus. Then the small twist drill begins to pierce the mother's uterus and drill in. Some mothers will feel a stabbing pain in the lower abdomen from time to time, and there will be a little red blood stain on the underwear, which is the blood flowing from the drilled area. At this time, the small cells can become embryos, have already differentiated into nearly 100 cells, and have begun to secrete the chorionic growth hormone HCG. And as time goes by, your metabolism increases.

How many days does it take to detect pregnancy?

Generally, the result can be detected by testing 7-10 days after sexual intercourse, and the longer the time, the more accurate it is.

The principle of pregnancy test strips is to test the HCG value, that is, the value of human chorionic gonadotropin in the body. This type of hormone is produced by the embryo and usually appears in the urine immediately after a few days of pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it will become increasingly obvious from 10 to 14 days.

What are the ways to detect pregnancy?

1. Test for pregnancy using test strips in early pregnancy

This is the most common way for everyone. It can be detected at the first 7 days after intercourse, usually 18 days, and rarely it takes 20 days to detect. 7 to 10 days after menstruation is to make the test results more accurate. The best time to take a sample on-site is 18 days after sexual intercourse, or 7 to 10 days after the next menstrual period is delayed.

2. HCG test in blood or urine

But it can be diagnosed at the beginning whether it is an unmarried pregnancy. When the sperm and egg combine and embed into the uterus, the pregnant woman's body produces a new hormone called chorionic gonadotropin, which helps to maintain pregnancy. This type of growth hormone can be detected in urine about 10 days after conception. Early pregnancy blood tests measure the amount of human chorionic gonadotropin in the blood, not the urine. Blood tests can detect very small amounts of male hormones, so they can detect pregnancy earlier than urine tests (usually about 6 to 8 days after ovulation).

3. Ovulation temperature test method

Use the ovulation temperature measurement method to test, measure your body temperature in bed after waking up every morning. The body temperature at this time is called the ovulation temperature. Generally, the human body temperature is below 36.5 degrees before ovulation. After ovulation, estrogen rises and acts on the human body temperature nerve center, causing the body temperature to rise by 0.3-0.5 degrees. If the egg cannot be fertilized, the estrogen level will decrease after about a week and the body temperature will return to normal. If pregnancy has occurred, the estrogen level will remain high and the body temperature will also remain high. If the high temperature curve of ovulation temperature lasts for more than 18 days, it can generally be confirmed that it is early pregnancy.
