A pregnancy test strip with a vaguely visible second line should mean that you are pregnant. If you want to be sure, you can go to the hospital and have blood drawn to check for HCG. Two lines on a pregnancy test strip is usually pregnancy. However, due to the quality of the test paper, operation irregularities and other circumstances, there may be errors, in order to ensure the accuracy of the results, you can go to the hospital to draw blood to check HCG, if the results are also positive, it is pregnant. Elevated HCG only indicates pregnancy, but does not determine whether it is intrauterine or extrauterine. Women can go to the hospital for an ultrasound around 6 to 7 weeks of pregnancy to check if the gestational sac is intrauterine, and at this time the embryo buds and the fetal heart may also be visible, which will make sure that the embryo is viable. In early pregnancy, it is important to take care of your nutrition and maintain a healthy routine. Pay attention to your own safety and do not fall.
