How long after sex can I detect pregnancy?

How long does it take to detect pregnancy after having sex? There are many female friends who want to become mothers as soon as possible and want to understand this issue well and want to know early whether they are pregnant. Generally, the best time to test whether you are pregnant is one week after your menstrual period stops. However, some female friends may not have a regular menstrual cycle, so if you test at this time, the result may not be positive.

In other words, for female friends with irregular menstrual cycles who want to test whether they are pregnant, it is best to find their ovulation time. Once they know their ovulation time, they can calculate it based on the time required for conception and find the time to test for pregnancy.

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 the sperm and egg meet, it can be shown in the HCG in the blood. So afterwards, just go to the obstetrics and gynecology department of the hospital to check a blood HCG test.

Therefore, a blood HCG test can be performed about 9-11 days after having sex during the ovulation period to confirm whether you are pregnant. Generally, an early pregnancy test can be used to detect whether you are pregnant one week after your period is delayed. A pregnancy test or B-ultrasound examination 35 days after conception can confirm whether you are pregnant.

Know how long it takes to detect pregnancy after having sex. If you can accurately find your ovulation period, you can test whether you are pregnant by testing about 10 days after ovulation. Another method is to use ovulation test strips for testing. If the ovulation test strips show double bars all the time after ovulation, then you may be pregnant.
