How long after sex can I use ovulation test strips to detect pregnancy

If you want to use ovulation test strips to detect whether you are pregnant, you need to master a certain period of time. Testing too early will not produce accurate and effective results. Generally speaking, you can check whether you are pregnant by using an ovulation test strip seven days after your period is delayed, or 10 days after having sex. Below, we will introduce you to the relevant knowledge about pregnancy testing.

1. How long after having sex during ovulation can you detect pregnancy?

Generally, it can be detected by using an early pregnancy test strip 7 days after the menstrual cycle is delayed or 10 to 14 days after sexual intercourse.

How to check: Two red lines appear on the test paper, indicating positive, which means pregnancy. In addition, you can go to the hospital for a blood HCG test 7 days after having sex during ovulation. This is the most accurate way to check pregnancy.

2. Why use test strips to detect pregnancy

1. 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.

2. HCG begins to be secreted on the 6th day after the egg is fertilized and can usually be detected after 11 days. The secretion of HCG increases rapidly in early pregnancy, doubling in about 1.7-2 days, while HCG cannot be detected in the urine of normal non-pregnant women.

3. 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.

4. 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. Under normal circumstances, 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.

5. The possibility of pregnancy is high during ovulation period. You can check with an early pregnancy test strip or draw blood for HCG two weeks after sexual intercourse. You can also go to the hospital to check your blood HCG level 7 days after your period is delayed to confirm whether you are pregnant.

3. Experts remind

(1) Although many types of early pregnancy test strips indicate that women can do a pregnancy self-test one day after missing their normal menstrual period, in fact, not all pregnant women release HCG hormones at the same speed and in the same amount. This varies from person to person.

(2) If a urine test is done too early, the negative result may be false. It is best to do a pregnancy self-test two weeks after your period is late, so that the result will be more reliable.
