Pregnancy test is a simple tool to prove if you are pregnant by testing the level of human chorionic gonadotropin. When a person is pregnant, the chorionic gonadotropin level in the body rises rapidly and is also present in the urine. You can determine if you are pregnant by taking a certain amount of urine and placing the test strip or pregnancy test in the urine without much time and observing the change in the test strip. If the test paper shows 2 clear red bars, it basically indicates intrauterine pregnancy. If there are 2 red bars and one of them is not very clear, there are three possibilities: 1) the pregnancy is relatively short; 2) there is biochemical pregnancy; 3) it may be ectopic pregnancy. If there is only 1 red bar on the test paper, it indicates that there is no pregnancy. Be sure to use a quality early pregnancy test paper or pregnancy test stick for testing.
