How many days of intercourse can the test paper detect?

If a couple does not take contraceptive measures when having sex, then they are preparing to have a baby.

How many days of intercourse can the test paper detect?

Many female friends will start preparing for pregnancy after marriage, but they don’t know what the symptoms of pregnancy are. Generally, for women who have had sexual relations, the most obvious symptom of pregnancy is delayed menstruation. Generally, if you find that your menstruation is delayed for a long time, you can use an early pregnancy test strip to test. So when can you test that you are pregnant?

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

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

Once the male sperm and the female egg combine to form a fertilized egg, about 7-10 days after the fertilized egg implants in the endometrium, the placenta of the pregnant woman will secrete a special substance called human chorionic gonadotropin, which is often referred to as hCG in medicine. It only exists in the body of pregnant women. About a week after pregnancy, human chorionic gonadotropin will appear in the urine of pregnant women, but in the first few days of pregnancy, the secretion of this substance is relatively small and difficult to detect. It is usually more obvious 10-14 days after pregnancy.

Generally speaking, about 18 days after normal sexual life, you can determine whether you are pregnant by testing urine, especially morning urine. The earliest time to detect whether you are pregnant is one week after sexual life, and the latest time is about 3 weeks.

What to use to test pregnancy after conception

The first one is the early pregnancy test paper

Using early pregnancy test strips, it can be detected at the earliest 7 days after intercourse, usually 18 days, and in some cases more than 20 days. 7 to 10 days after menstruation is to make the test results more accurate. The best time to test is 18 days after intercourse, or 7 to 10 days after the next menstruation.

The second method is the basal body temperature test method

Use the basal body temperature measurement method to measure your body temperature in bed after waking up every morning. The temperature at this time is called the basal body temperature. Generally, the body temperature is below 36.5 degrees before ovulation. After ovulation, the progesterone level rises and acts on the body temperature center, causing the body temperature to rise by 0.3-0.5 degrees. If the egg cannot be fertilized, the progesterone level will drop after about a week and the body temperature will return to normal; if pregnancy has occurred, the progesterone level will remain high, causing the body temperature to remain high as well. If the high temperature curve phenomenon in the basal body temperature persists for more than 18 days, early pregnancy can generally be confirmed.

The third type is a blood or urine HCG test

When the fertilized egg is implanted in the uterus, a new hormone called 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.

Therefore, female friends who have had sexual relations must pay attention. If you find that your menstruation is late, the first thing to consider is the possibility of pregnancy. You can buy pregnancy test strips at the pharmacy for testing. If you are not confident about the test results, you can also go to the hospital for professional examination. Don't take it lightly.
