How many days after ovulation can pregnancy be detected?

The principle of pregnancy test is to detect human chorionic gonadotropin (hCG) in the body's urine. Generally, trophoblasts begin to secrete a small amount of hCG on the 6th day after ovum fertilization, and hCG can be detected in the blood about 1 day later. This is the most sensitive way to detect pregnancy, and the positive hCG reaction in urine will appear later than in blood.

Although many pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period, in fact, the sensitivity of each pregnancy test strip is different, and the test varies from person to person. Initially, you can check whether you are pregnant based on blood hCG 7-10 days after ovulation, but because the amount of hCG is small in the early stages of pregnancy, it is not easy to test it out. If you use a pregnancy test strip, you can check whether you are pregnant half a month after ovulation. If you are in early pregnancy, it is best to use morning urine for the test. Because of the extraction of morning urine, hCG levels are higher.

Generally, a test 2 weeks after intercourse can confirm whether you are pregnant. The time for B-ultrasound detection of early pregnancy is usually about one week after the menstruation is delayed. You can go to the hospital for a B-ultrasound examination to see if you are pregnant. If a high pregnancy score is seen under the B-ultrasound, it means you are pregnant. The early stage of pregnancy can be confirmed by testing blood HCG 10 days after intercourse. This is the earliest and most accurate testing method at present. For women who are planning to get pregnant, they can use basal body temperature measurement to detect whether they are pregnant. Generally, a blood hCG test 7-10 days after ovulation can diagnose whether you are pregnant. The pregnancy test paper will be more accurate if it is tested 14 days after ovulation.
