Pregnancy tests are best done with the first urine test in the morning, because they mainly look for the presence of chorionic gonadotropin in a woman’s body. When the level of this hormone is high in the body, it will show up in the urine. The first urine in the morning is more concentrated, when the woman has not drunk a lot of water, so the concentration of the hormone is relatively high, and it is more accurate to check for pregnancy at this time. In addition, the best time to test with a pregnancy test is half a month after intercourse. If the test is done too early, the hormone level in the woman’s body will be low and the test will easily be a false negative. If it is 14 days after intercourse, the hormone level in the body is higher and if it is pregnant, it should be able to detect it.
