If you test with an early pregnancy test, that’s usually about two weeks after intercourse during ovulation to detect if you’re pregnant. Testing urine with early pregnancy test strips is a relatively common method of detecting whether you are pregnant, usually about two weeks after intercourse during ovulation. However, when testing, it is best to choose morning urine, which is the first pee after waking up in the morning, as it is relatively accurate. If there is one bar in the control area and one in the test area when the test is done correctly with a certified pregnancy test strip, this is a positive result and indicates pregnancy. If there is only one bar in the control area, this is a negative result and indicates that you are not pregnant. If there is only one bar in the test area, this is an invalid result and does not determine pregnancy. The results of urine tests using early pregnancy test strips are not 100% accurate. To determine if you are pregnant, you can also take a blood test for human chorionic gonadotropin (HCG) about 10 days after intercourse during ovulation, which is one of the most sensitive tests for determining early pregnancy.
