How many days after sex can you test for pregnancy

We all know that if a woman who has a normal sex life misses her period, she may be pregnant. So how long does it take to detect pregnancy after having sex? Generally, pregnancy can be confirmed by taking a blood test for HCG 8-10 days after intercourse. Generally speaking, pregnancy can be detected by using an early pregnancy test strip about a week after the menstrual period is delayed. Generally, blood tests and B-ultrasound examinations are the most accurate way to confirm whether you are pregnant. Blood tests can also be done after the embryo has implanted to confirm it.

In medicine, the time of pregnancy is generally calculated from the first day of the expected date of delivery. If you use B-ultrasound examination, generally speaking you can see it in 35 days, but for some women, due to late fertilization and late implantation, it may take about 40 days to see it. Therefore, the latest period will not exceed 40 days.

After a woman becomes pregnant, HCG will be present in her blood and urine. hCG enters the maternal blood around the sixth day after fertilization and multiplies rapidly until the eighth week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains there for a long time. If you suspect you are pregnant, you must go to the hospital for blood tests, HCG tests, B-ultrasound tests, urine tests and other related tests to confirm whether you are really pregnant. If you are indeed pregnant, determine whether it is an intrauterine or ectopic pregnancy, and then take corresponding measures.

Symptoms of early pregnancy include cessation of menstruation, tingling, swelling and itching in the breasts, nausea and retching, frequent urination and urgency. There are other manifestations of early pregnancy, such as changes in skin color: causing skin pigmentation or stretch marks in the abdomen, which are more obvious in the late pregnancy. Vaginal mucosal discoloration: In early pregnancy, the vaginal mucosa may appear darker due to hematoma. Very easy to get tired: In the early stages of pregnancy, you will get tired very easily and often feel sleepy.

How to detect pregnancy?

There are generally four ways to check whether you are pregnant: urine test, ultrasound test, regular blood test and gynecological examination. Urine test is the most common way to test, and you can test at home using pregnancy test strips, or you can go to the hospital for testing. To increase accuracy, it is best to use morning urine test. B-ultrasound examination is a quick and accurate way to diagnose early pregnancy. Intravaginal ultrasound can diagnose early pregnancy one week earlier than abdominal ultrasound. The presence of a gestational sac in the uterus is the first image to appear during ultrasound diagnosis. Your doctor may also recommend a blood test, usually done within a week of your first menstrual period. A gynecological examination should confirm pregnancy 40 days after menstruation stops.

It takes some time to test whether a couple is pregnant after having sex. The egg begins to secrete HCG on the 6th day after fertilization. A blood HCG test 9-11 days after intercourse can diagnose whether you are pregnant. If you use an early pregnancy test strip, you can detect it two weeks after sexual intercourse. Morning urine should be used for the test, which is more accurate, so you can know whether you are pregnant at the earliest time.
