How many days can I detect pregnancy?

Many women are inevitably excited when they are pregnant for the first time, so women are always so curious for the first time. A few days after having sex, women will observe their symptoms to see if they are pregnant. However, the symptoms of pregnancy may appear very late, making it impossible for women to confirm. Many women want to know how many days after having sex to test whether they are pregnant. So how many days can it be tested?

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.

If you don't believe in this method of testing pregnancy, you can also choose to go to the hospital for a routine urine test. Based on the routine urine test, you can determine whether you are pregnant. However, you must hold your urine during the first routine urine test, because the fetus is not fully developed at this time. If necessary, you must also do a B-ultrasound examination. These medical examinations can accurately determine whether you are pregnant or not.
