How long after conception can I use test strips to detect

Many female friends start to prepare for pregnancy after getting married, but they don’t know what the symptoms of pregnancy are. Generally, for women who have had sex, the most obvious symptom of pregnancy is delayed menstruation. Generally, if you find that menstruation has been delayed for a long time, you can use a pregnancy test strip to test. So when can you detect that you are pregnant?

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

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

Once the man's sperm and the woman's egg cell combine to form an egg and sperm, the embryo will secrete a special substance called human chorionic gonadotropin (hCG) about 7-10 days after the embryo implants in the uterine wall. It only exists in the pregnant woman's body. About a week after pregnancy, human chorionic gonadotropin will appear in the pregnant woman's urine, but in the first few days of pregnancy, the secretion of this substance is relatively small and it is not easy to be detected. It is usually more obvious 10-14 days after pregnancy.

Generally speaking, about 18 days after a normal sexual life, you can determine whether you are pregnant by testing urine, especially morning urine. After sexual intercourse, you can test whether you are pregnant within the first week, or at the latest about 3 weeks.

Which pregnancy test to use after pregnancy

The first one is the early pregnancy test paper to test pregnancy

Use pregnancy test strips to test. Using pregnancy test strips, it can be detected 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.

The second method is to test the body temperature during ovulation.

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 already 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.

The third method is HCG test in blood or urine

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.

Therefore, female friends who have experienced sexual intercourse must pay attention. If you find that your period 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 very satisfied with the test results, you can go to the hospital for professional examination. Don't take chances.
