Many people want a baby to add a little life to their family shortly after getting married. So I actively prepared for the arrival of the baby, but after having sex, I didn't know if I had successfully conceived, and I was very anxious. I want to know the result as soon as possible, and if it's not successful, prepare for the next time. So, how long can pregnancy be detected?
Generally speaking, self testing can be done 7-10 days after sexual intercourse, using early pregnancy test strips or pregnancy test sticks to test pregnancy through morning urine. The longer the time after sexual intercourse, the more accurate the test. In short, after sexual intercourse, pregnancy can be detected within the first week and at the latest about three weeks.
Because pregnancy testing is generally determined by measuring the concentration of HCG in the blood or urine, which is the concentration of human chorionic gonadotropin. However, the changes in HCG concentration in the blood and urine after pregnancy go through a process, so the longer the time after sexual intercourse, the more accurate the test will be. To further confirm the diagnosis, it is necessary to go to the hospital for testing, and pregnancy can also be detected by ultrasound after one month.
At present, the most intuitive and clear way to determine the gender of the fetus is through ultrasound examination. Generally, around 4 months of pregnancy, the gender of the fetus can be determined through ultrasound examination. At the end of the 12th week of pregnancy, the external genitalia of the fetus have already developed. By the end of the 16th week, the gender of the fetus can be determined from the external genitalia. During the examination, the fetal position should also be taken into account. When the fetal position is good, the judgment is more accurate. Therefore, when using ultrasound to determine the gender of the fetus, it is influenced by the doctor's experience and fetal position.
