How many days after sex can pregnancy be detected

How many days after having sex can you detect pregnancy? Many women who are preparing for pregnancy want to know this question after ovulation every month, so that they can know whether they are pregnant as soon as possible. In fact, when it comes to the current methods of testing whether a woman is pregnant, although the early pregnancy test strips are the most common and convenient, if you want to make an accurate judgment, it is best to draw blood to test the HCG content in the blood.

As for the question of how many days after intercourse it is possible to detect pregnancy, different testing methods require different times. If it is a blood test, generally a significant increase in the HCG level in the blood can be seen one week after conception. You can analyze the specific time based on the conception process.

How many days after sex can pregnancy be detected

1 day after fertilization

It takes a certain amount of time for the discharged egg to reach the ampulla of the fallopian tube, where it waits for the sperm, generally about 10 hours, which means that fertilization occurs within 12 hours after ovulation; the moment when the sperm and egg meet and fertilize is called fertilization, and the process of sperm and egg fertilization itself takes about 12 hours, which means that the whole fertilization process needs to be completed 24 hours after ovulation;

7-8 days after conception

It takes 7 to 8 days for the fertilized egg to swim from the abdominal wall of the fallopian tube to the uterus and implant in the mother's body, which is when it is called conception. Therefore, it takes at least 7-8 days from fertilization to pregnancy, but no more than 9-10 days, because if it exceeds 10 days, the corpus luteum will retreat, progesterone will withdraw, and menstruation will come again.

HCG is produced 7 days after fertilization

Human chorionic gonadotropin (HCG) is a glycoprotein hormone produced in the body of pregnant women and exists in large quantities in the blood and urine of pregnant women. HCG begins to be secreted on the 6th day after the egg is fertilized and can usually be detected after 11 days. In early pregnancy, the secretion of HCG increases rapidly, doubling in about 1.7-2 days, while HCG cannot be detected in the urine of normal non-pregnant women. Therefore, detecting HCG in urine is a reliable indicator for determining pregnancy. If you are newly pregnant, it is more accurate to use morning urine. Generally, a check-up two weeks later can confirm whether you are pregnant.

After knowing how many days after having sex you can detect pregnancy, it is recommended that women who are planning to have a baby, if they do not want to go to the hospital for blood tests, but want to know whether they are pregnant early, can use ovulation test strips to test when they should have their period. If the result is positive, it can still be determined whether they are pregnant.
