The presence of two bars on a pregnancy test indicates pregnancy. If you are not pregnant, the pregnancy test will not indicate that there are two bars, and as long as the test result is accurate about 12 days after intercourse, it means that you are pregnant, and the accuracy rate may be about 98% under normal circumstances, with a very small chance of error. If you are particularly unsure, you can go to the hospital for a blood test for human chorionic gonadotropin, which will give you a more accurate result. If you want to continue the pregnancy, it is recommended to pay attention to the pregnancy checkups, and you can go to the hospital for a black and white ultrasound when you are about 42 days pregnant to check the development of the fetus. If you want to terminate the pregnancy, you should also go to the hospital for an ultrasound when you are about 42 days pregnant. As long as the size of the gestational sac is 1cm or more, you can have an abortion or medication abortion at this time.
